PWM Solar Charge Controller 12V/24V/48V 40A
This 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.

1.Make sure your battery has enough voltage for the controller to recognize the battery type before first installation.
2.The battery cable should be as short as possible to minimize loss.
3.The regulator is only suitable for lead acid batteries: OPEN,AGM, GEL it is not suited for nickel metal hydride, lithium ions or other batteries.
4.The charge regulator is only suitable for regulating solar modules. Never connect another charging source to the charge regulator.
1.Connect the battery to the charge regulator - plus and minus.
2.Connect the photovoltaic module to the regulator - plus and minus.
3. Connect the consumer to the charge regulator - plus and minus.
(The reverse order applies when deinstalling! An improper sequence order can damage the controller)
