Product description: Solar PWM charge controller with LCD display AZO Digital SOL-30ED 12/24 - 30A
TheAZO Digital SOL-30EDsolar PWM controller has been equipped with an LCD display. It is a kind of inverter, which is used to control the operation ofphotovoltaic systems. Its task is to ensure proper characteristics of thebatterycharging current, protecting them from too deep discharge or overcharge. Solar controllers guarantee that the battery life in the solar panel / battery system will be increased. The SOL-30ED controller supports input voltages of12 V and 24 V,maximum charging current of30 A,supportsgel / AGM batteries. AZO Digital SOL-30ED protects the battery against too deep discharge by disconnecting the energy source once the critical voltage for the battery exceeds11 V. When the battery is fully charged, the regulator disconnects the power supply from the photovoltaic panels when the battery voltage reaches14 V - 14.5 V.
