Photovoltaic charge controllers or voltage regulators control the amount of energy from the PV panels going into the batteries. In particular they protect the batteries from overcharging, subsequent gassing, loss of electrolyte and possible plate damage.
These sophisticated solar charge controllers all include pulse width modulation (PVM) series charging; temperature compensation 25% design margin for overloads; high efficiency and low self-consumption. Overvoltage; reverse polarity, short circuit and lightning protected. Operating temperature range of -40 to 85°C. Five year warranty
Robust & powerful maximum power point (MPPT) charge controllers
