The incorporation of batteries in photovoltaic installations is not usually done for profitability reasons, but to have energy independence, to have energy in areas where the grid does not reach, or to guarantee energy supply in case there are problems in the grid.
If this is your case, you are in good hands. The battery systems we assemble are modular and of high quality. We base the storage systems with UPS function(back-*up) on the solutions that the Dutch manufacturer Victron Energy offers us. All this means that, if there is a grid outage, the customer will not be left without power.
In addition, during maintenance spots, we check the condition of the batteries and contact the manufacturer in case we observe any anomaly in order to activate your product warranty.
