charging system
Replace the battery power of the MURA (Mini Usina Rural Autonomous) is a theme that helps to understand the concept of Independent Power Plant. As often happens, the smaller and simpler the system easier to understand the basics. A cabinet of 25 x 30 x 45 cm notebook, everything in sight, no distractions, can ask ... but where is the electricity? The larger the accumulation system more confusing and less significant have. Even the experts are surprised and recognize their surprise. No wonder. Electricity have the same characteristics as the network of Public Service, with the addition of phase is also in a permanent phase and and, 24 hours, is a real solution for those without access to the network. participate in a demonstration and proceed to the electric starter and automatic shutdown of the motor 5 HP two-stroke self-excited generation 3 x 220 V, a pseudo 2 HP alternator only nominal, it is not common. Watching a little engine of 70 cc displacement triggering a three-phase submersible pump 3 HP drawing more than 20,000 gallons of water time, is unusual. The expressions we hear daily in the demonstrations really fill us with satisfaction and reward our efforts and dedication in conjunction with electrical power for individual use. Also when talking about the replacement battery charge surprises are no less than in the first stage. No less than seven alternatives are available to charge users to replenish the energy and start a new cycle of service. Here is a summary of them to go to the particular analysis.

-
A wind turbine - A hydraulic microturbine
- The alternator of the vehicle itself
-
existing Generator - self-excited alternator Kama / Windy West
- Public Service Line
- Alternator euripodinámico
As ob
saw the first condition, although it seems a truism, is that the location of the miniusina there is sufficient wind. The second is that the tension generated, unlike 99% of boys wind turbines, up to 2.5 meter diameter propeller, either single or three phase 220 volts. The third condition is that this fitted with a charge controller so as to interrupt after reaching the maximum level. An important observation is that, even though the fuel is free, as in hydropower, the investment is higher than in the other cases. Commercially speaking, the term of this unit wind that meets those requirements is our WW 3IP of 1.80 meters in diameter, ceramic magnets, 220 V twin-bladed or even the 6 WW 2.5-meter three-bladed, self-excited 3 x 220 Volts. hydraulic Microturbine
As in the previous case, it is necessary to have a waterfall and a flow, typical of Andean places .. The product obtained by multiplying the height in meters of 
leap flow in liters per second should not be less than 80 to contemp lar load with this system. As in the previous case, the installation is not cheap, but the fuel is a gift of nature, but compared with wind power has the advantage that there is almost * natural intermissions. Can be expected that water flow is constant during most of the year, with an energy utilization factor very different from the previous case in which rarely can exceed 30%.

Over 50% of the time is used for moving between different points of access. Use the engine alternator as a means of charging storage system is an excellent alternative. Harnessing the strengths of the voltage regulator, with proven effectiveness, is an irresistible temptation. The only precaution is to check that the alternator is capable of absorbing extra work. In general almost all vehicles have sufficient capacity to absorb it. In the worst cases you will need to change the alternator with one of sufficient capacity. A transformer, sandwiched between the alternator and battery system will raise the 3 x 11 volts AC. delivered by the alternator to 220 VAC required for charging. The internal connection in the alternator can make an electrician smoothly by following our instructions.

The miniusinas solve this problem and is acceptable to continue with the old system put in place for six or seven hours the group, which in turn will charge the batteries of the mini, which stopped after the running of the group, to be responsible to continue service without interruption until the next day. In over 90% of cases you will not need any modification. However, to complete 100% you only need supply a booster especially in cases where the voltage of the generator of the group, no sea senoidal o el regulador de voltaje impida un acople adecuado.

Alternador Autoexcitado Kama / Windy West
Es el mas espectacular y efectivo complemento de la Miniusina. El motor de impulso de solo de 200cc., cuatro tiempos, de probada eficacia. El alternador es un simple motor jaula de ardilla trifásico autoexcitado, sin escobillas ni colector ni anillos rozantes, totalmente exento de problemas de mantenimiento. Dotado de arranque eléctrico, se interrumpe su marcha automáticamente cuando se alcanza la tensión de carga completa de las baterías, virtud que le confiere la seguridad y comodidad indispensables para la protección de las baterías and fuel economy.

Properly combining the use of hand throttle, the ammeter and the automatic stop control allow, for example, power all the time necessary submersible pump without personal attention. An important observation is that, as in the case of the generator itself, the charging source is removable, which does not happen with the microturbine, the turbine or the public service line. Consumption Mixing estimate is 400 cc per Kwhora generated.

When you want to use the emergency system MURA as unplanned outages to the service or for short periods such as on a weekend or as a transitional source for maintenance in field, the load can be made directly from the 220 volts. It is also possible to use as a UPS (Uninterrupted Power System) for the use of computers or any other service where a power failure is unacceptable. Alternator Euripodinámico

the s s natural source of renewable energy, and as a result of wind, boating enthusiasts have an important alternative, wave energy, unlike wind, does not interfere with motion of the boat, minus the effective displacement energy. Ideal resource for coastal beacon. The condition, as in the wind and water is the source of generation is at 220 volts. If it were not so, as in the case of the box stock alternator will need to convert a transformer.
One last comment for those who have suggested sunscreens such as power supplies alternative. It is technically possible but completely discarded for economic reasons. Supply 200,000 liters of water daily, be feasible with the Mura 2300, would involve an investment of at least 240 times compared to the little motor Zanella / WW making it impossible to justify, even taking into account fuel consumption and maintenance.
This system is appropriate for the use of a RAMPP / MURA in a recreational vehicle (RV), motor home, camper or travel trailer with either touristic or work related purposes. For the traveling salesman, social worker, inspector, technician or simply a tourist, the RV can become a workshop, office, bedroom or kitchen in need of electricity. With usually over 50% of the time used up driving from place to place, the use of the engine alternator as a charging system is more than convenient. Moreover, to put to use the tested effectiveness of the voltage regulator is irresistible. The only thing to keep in mind is to make sure that the alternator has enough capacity to perform an extra task; if it does not, a slight modification that can be performed following our simple instructions or by an electrician will be necessary. By installing a transformer between the alternator and the battery system, it will be possible to take the 3X11,6 volts delivered by the alternator to the 3 x 220 VCA needed to perform the battery charge.

Rural Autonomous Mini Power Plants (RAMPP)
Charging systems
Replenishing the battery charge of a Rural Autonomous Mini Power Plant (RAMPP or MURA for the initials in English) is helpful in order to grasp the principle of an Autonomous Electric Plant. As often, the simpler and smaller the system, the easier it is to understand its basics.
The sight of a portable cabinet of 25 x 30 x 45 cms., plain and simple in appearance, prompts the question: Where does the electricity come from?. Larger accumulation systems might be more imposing but certainly less effective in its results. Even the most skilled experts in the energy field are taken aback by the concept of the mini power plant. And rightly so; the provision of permanent electrical power 24 hours a day, the possibility of enjoying the same advantages of those connected to the national electricity grid, in addition to supplying single-phase and three-phase current, is a dreamlike solution for those unable to join the national electricity network for geographical reasons.
It is equally startling to take part in a demonstration of the remarkable RAMPP/MURA features: Its electrical start up and automatic stops of a 3 HP two-stroke motor propelling a 2 kva self-exited squirrel cage induction alternator are rare and unusual. The practical demo is hard to believe: It is truly astonishing to watch a tiny engine of a 70 cc cylinder capacity propelling a three-phased submergible pump extract over 20.000 liters of water per hour. The puzzled comments we have grown used to hearing during each demo are indeed a heart-warming award to our efforts and commitment to our project of individual electrical power usage.There is also the crucial subject of replenish the batteries charge, that usually provokes the same surprised remarks from our customers. Our RAMMPs / MURAs are flexible enough as to offer no less then seven different alternatives to recharge the batteries in order to start a new service cycle. Here is brief overview of each one:
Wind mill generator
There are three major conditions that need to be met in order to replenish the RAMPP/MURA battery charge by means of a wind mill generator. First and almost needless to mention, it is necessary to install the device in a gusty winds area. Secondly, the generated tension must be single-phased or three-phased 220 volts (most small dimensions wind mill generators of a helix diameter up to 2.5 mts. only generate 12 or 24 Vcc). Lastly, the wind mill generator must be furnished with a charge regulator that will interrupt the process once the battery is fully recharged.
It is also important to point out that although the operation expenses of the wind mill generator will not be high since the fuel (the wind) is obtained for free, the initial investment for this equipment will be considerable.
Mini-Hydraulic Turbine
Naturally, an abundant waterfall such as those common in mountainous areas is essential for the use of this method. In order to consider the use of a mini-hydraulic turbine, it is necessary to multiply the waterfall height in meters by the water caudal expressed in liters per second. For this system to be applicable, the product must be a number above 80.
Although the initial investment for this system is considerable, its fuel is obtained freely from nature and, as opposed to wind power, hydraulic power is constant and does not present natural intermittences. The flow of water can be expected to remain consistent for most part of the year, resulting in an energy exploitation factor much higher than the use of wind power, which rarely surpasses 30%.
The Alternator of a mobile vehicle
This system is appropriate for the use of a RAMPP / MURA in a recreational vehicle (RV), motor home, camper or travel trailer with either touristic or work related purposes. For the traveling salesman, social worker, inspector, technician or simply a tourist, the RV can become a workshop, office, bedroom or kitchen in need of electricity. With usually over 50% of the time used up driving from place to place, the use of the engine alternator as a charging system is more than convenient. Moreover, to put to use the tested effectiveness of the voltage regulator is irresistible. The only thing to keep in mind is to make sure that the alternator has enough capacity to perform an extra task; if it does not, a slight modification that can be performed following our simple instructions or by an electrician will be necessary. By installing a transformer between the alternator and the battery system, it will be possible to take the 3X11,6 volts delivered by the alternator to the 3 x 220 VCA needed to perform the battery charge. Power Plant
Over 80% of the people unable to connect to the national electricity grid have worked out their problem utilizing a small home power plant, their only problem being the supply intermittence. RAMMPs do not present this problem. It is absolutely acceptable to put the power plant to work for six to seven hours daily with the only purpose of replenishing the RAMMP batteries, not to provide an electricity supply.
Once the power plant stops functioning, the RAMMP will be able to provide continuous electricity for the rest of the day. In over 90% of the cases, no alterations to the power plant are necessary in order to recharge the RAMMP batteries; however, for the remaining 10% a voltage elevator might be needed if the power plant alternator tension is not sinusoidal or the voltage regulator hinders a proper coupling.
Self-excited alternator
This is by far the most effective and impressive addition to any RAMMP. The driving engine of 50/70 cc two strokes is highly efficient and similar to the motor used by a scooter. The alternator is a basic self-excited three phased squirrel cage motor, without brushes, collectors, slip-rings or complicated maintenance pieces. Furnished with an electrical start up mechanism, its operation stops automatically once the batteries are fully replenished. This unique feature gives the system unparalleled safety and convenience properties, key to the batteries protection and the fuel consumption. The cost of this alternator amount only to 25% of the cost of a similar capacity small power plant, weights a total of 23 kgs. And allows the usage of up to a three-phased engine of 3HP autonomously, without any aid from the batteries. By properly combining the use of the manual accelerator, the control ammeter and the automatic stop, it is possible to operate, for example, a submergible pump without constant supervision. It is important to note that both the alternator and the power source are mobile, as opposed to other methods such as the wind mill generator, the micro turbine or the power grid.
The estimated gas consumption amounts to 400 cc per Kw hour generated.
Public Grid
When it is intended to use the RAMMP as a back up emergency system in case of blackouts, or for short periods of time such as weekends, or as a temporary power supply to perform maintenance work on the land, it is possible to replenish the batteries by using the public 220 volts national grid. It is also possible to use the RAMMP as a UPS (Uninterrupted power system) to provide for mainframes or any other service that has no tolerance for a blackout.
Swell Power alternator
Navigation fans have yet another source of renewable energy at their disposal: the energy of the waves. Unlike wind power, the waves power does not hinder the embarkation movement, therefore not subtracting energy of any kind from the actual embarkation movement. The only condition remains, as of water and wind power, the generation source must be 220 volts or a transformer will be necessary.
As a footnote for those suggesting the use of photovoltaic cells as an energy alternative, although technically possible, we do not find them acceptable due to economic reasons. To be able to supply 200.000 liters of water daily as the RAMMP (MURA) 2300 does, solar screens would require 240 times as many an investment that a RAMMP (MURA) would. An unacceptable amount in spite of any fuel or maintenance figures.
