In any case,
Greentronics REPOWER KIT is the solution to your energy problem.
enormous advantage of a photovoltaic storage system today is to avoid
the purchase of the electrical energy from the energy provider (as the
energy produced can be stored to be used especially in the
evening hours, when it is really necessary), rather than producing it
to sell it to the energy provider (unless it is consumed
instantaneously, but only during daylight hours) at a much lower (and
fluctuating) price, that is about one third of the cost of purchase.
Our innovative REPOWER system allows to realize modular
photovoltaic storage systems of any size, in islanding (OFF GRID) so
even without any connection with the mains, to achieve total energy
independence, maximizing self-consumption and completely freeing up
yourself from the bills. It is also compatible with a single-phase or
3-phase generator, with manual or automatic starting (ATS) to assist in
emergency situations that may occur after several days of overcast.
It allows the use of any type of lead batteries (AGM, GEL, free
acid, deep cycle, etc.), as it is equipped with an automatic
desulfation function that provides to desulfate (i.e. remove the lead
sulfates from the electrodes) each single battery only when it is
necessary, reporting every day the batteries in optimal conditions.
The REPOWER KIT system is
therefore it is possible to realize system configuration with multiple
power or anyway with minor or higher power, purchasing separately its
components and assembling them properly.
Thanks to the possibility to use very cheap batteries such as
common lead acid batteries, thanks to special commercial agreements
signed with the best European producers of photovoltaic panels and
batteries, thanks to the economies of scale that derive from the
modularity of the system, thanks to our vertical commercial approach
addressed directly to the customer, we have an unbeatable price for the
entire system, which is just about 1000€ per kWp, including
photovoltaic panels, batteries, charge regulators and concentrators.
This price already refers to a sizeable storage capacity, that is,
4,3kWh for each kWp of photovoltaic power.
This results in the lowest payback
time for a photovoltaic system: about 3,5 years
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.
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
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
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.
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.

HOME / RESIDENTIAL USERS
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 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
payeven the fixed costs of the bill.
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.
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
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.
