Charge regulators are installed on solar systems in Cyprus where generated power in stored in battery cells. This is the case with the stand alone systems where excess power is stored in order to be used over the night or during cloudy days where the production is limited. Battery cells shall be charged and discharged under controlled procedures in order to comply with the terms of usage given by the manufacturer and the guarantee policy. Excess charging and discharging can lead to shortening of the life cycle of your batteries. This is the exact role of the charge regulators.
