Instruction for SUN series solar system control box
Model: SUN-SP2500
1, Product Introduction
SUN series solar system control box is a set of integrated products, including solar charge controller, inverter, wiring terminals, control switches etc.
As long as connected to the matched solar panels and batteries, it would constitute a complete solar photovoltaic system that can serve as power supply. The output has two kinds of DC and AC, for DC load and AC load, it is very convenient to be used. Particularly it is suitable for the absence of power or less power regions.
The solar charge controllers in controller box, it can be automatically charge batteries subject to light conditions and status of the battery, fully intelligent, and it has function for over charge and over-discharge protection, thus greatly extend the battery life.
The inverter in the controller box can convert DC voltage of batteries into alternating voltage, to drive AC loads.
The control switches in control box control the output on and off, a total of 4 switches, of which an AC output control switch and a DC output control switch, plus a touch button, to control the total DC output and timing settings and other functions.
Control box also has a range of protection, can effectively prevent the damaged because of abnormal usage.
