Solar Panel Voltage Regulator 12V 20AThis versatile solar regulator is suitable for use with all types of photovoltaic panels and wet or sealed lead acid batteries. The internal microprocessor controller provides the optimal charging current and voltage according to the actual stage of charge and type of battery. The 3-stage (Bulk, Absorption & Float) charger ensures proper maintenance of lead acid type batteries, maximising their service life. For wet cells, there is an equalisation function, which automatically cycles the battery once a month for two hours. The unit also automatically disconnects the battery if the terminal voltage drops below 11.5V, and then reconnects it once it is charged again. It features an LCD panel that displays battery voltage, the solar panel voltage and the active charge mode. Unlike other regulators, you can see the true status of the charging system at a glance (e.g panel voltage, panel charging current, battery voltage, total ampere hour input to system...). Powerful Night-Light mode. The control can switch on a light (a 12V light connected to light terminals) at night time with programmable duration. Temperature sensor for the regulator sold separately and available in our shop. No extra handling and postage for temperature sensor if ship together with regulator. Features:
