In the discharge phase in a lead battery, a chemical reaction of lead sulfate production (PbSO4) occurs, resulting in an increase in the density of the sulfuric acid electrolyte solution (H2SO4). Lead sulfate being chemically a "salt", has a tendency to "crystallize" or to compact into a solid structure of high resistance that settles on the electrodes in an almost irreversible way.

In all lead batteries, after already a year of life, especially if subjected to prolonged discharges, long periods of downtime or for use at excessively low or excessively high temperatures, the sulfate process begins to block the passage of current between the plates and then between the elements of the battery, until it gets in this way to completely inhibit both the charge and the discharge of the battery.

The modular photovoltaic storage system REPOWER KIT is based on the high-efficiency 7-stage REPOWER PVG charging controller with automatic desulphator for 12V or 24V lead batteries, controlled by microprocessor and powered by photovoltaic panel. This device autonomously recognizes, thanks to its software with automatic diagnostic algorithm, if the battery to which it is connected is in sulfate condition, and, only in this case, automatically starts its particular process of desulfation at the resonance frequency of lead sulfate crystals, disintegrating them entirely, until the battery is fully restored. At that point, the REPOWER starts the normal charging process.

The time interval for the full charging of all batteries in the system depends on the power of the photovoltaic panels connected to the system and the capacity of the batteries used. With medium-capacity batteries (60Ah) and 275Wp panels, the entire storage system is fully recharged during a sunny day.

At the end of the charge, the REPOWER KIT storage system provides, separately on each individual battery, to provide the maintenance charge necessary to compensate for the natural discharge and to block the charge at the end of this last phase, to avoid gasification and progressive depletion of the electrolyte inside the batteries.

TYPICAL APPLICATIONS

HOME / RESIDENTIAL USERS

If you have an independent house with a terrace, a canopy, a flat or pitched roof or other outdoor space where you can place the photovoltaic panels, the REPOWER KIT system, if sized appropriately, can make it fully autonomous energetically. By connecting the output of the inverter to the entire electrical system of the house, if you want, you will be able to do without the energy supply contract and no longer pay even the fixed costs of the bill anymore thanks to the compatibility of the system with a generator unit that can take over on the cloudiest days.

CONDOMINIUMS

If you live in a condominium, you can install solar panels to serve individual real estate units on the common roof or on any other suitable common surface and on individual owned parts. In such cases, the assembly must, at the request of the interested parties, allocate the use of the roof and other common areas. In case the share of the roof intended for you is insufficient, that is less than 24 square meters, you can ask us for a personalized quote with photovoltaic panels from balcony or wall, especially if you have a balcony exposed to the South.

CAR PARKINGS

If you have a hotel, a restaurant or a supermarket with an outside parking, or more simply you want to equip your villa or condominium with a photovoltaic canopy, to power your home utilities or create attractive charging stations for electric vehicles, don't hesitate to ask us for a personalized quote.

RESORTS / ENERGY COMMUNITY

If you have a tourist village, a seaside resort, or you are about to buy a holiday home in a two-family or terraced cottage, perhaps in an area where the electricity supplier connection is too expensive, you can also install the REPOWER KIT in sharing with other nearby residents, in order to take advantage of additional solar surfaces and to take advantage of increased storage capacity. All this is always possible thanks to the modularity of our system.
