Portable Safety 30A 12/24V Solar Panel Battery Regulator Charge Charging Controller

Features:
This solar charge controller is great for household power generation system.
Made of high quality ABS material, not easy to aging, safe and durable, constructed with four holes for convenient installation.
When the battery voltage is low, the controller will automatically cut off the load from the system.
Safety systems provides overcharge protection, short circuit protection, over-load protection and lightning protection.
The controller will automatically compensate the temperature of the charging voltage according to the changes of ambient temperature.

Wiring Instruction:
1. Storage battery "+", "-": the 3rd, 4th terminal(from the left)
load indicator light flashes once and will light up after 15 seconds, which shows correct 
connection, otherwise it will cause damage to controller.
2. Solar panel  "+", "-": the 1st, 2nd terminal(from the left)
3. Load "+", "-": the 5th, 6th terminal(from the left)

Indicator Light Instruction:
1. Charge indicator light: light up showing it's at powerful charging status; flash showing it's at 
floating charging status; doesn't light showing that charging is finished.
2. Load indicator light: light up showing there is output, load can normally work; otherwise the 
load can't work.

Note:
1. Before wiring please check out the rated voltage of solar panel, storage battery, load carefully, ensure they are all 12V of voltage or all 24V.
2. Rated current of solar panel and load can not more than the rated current of controller(30A).
3. Do not directly use solar panel battery to power load.
4. Do not use light to charge solar panel, because it is insufficient when charging by light bulb.
