Product Introduction

Solar Charge Controller applies in solar photovoltaic systems, which coordinates the working of solar panels, batteries and loads. The series Solsum E IP68 continues the huge success of one of the most used SHS controllers. With a power range of up to 15A at automatically recognized 12v or 24V it fits to a system sizes of maximum 360W.

The circuit board is completely electronically protected and with the Led user interface it is easy to check the battery of charge at any time. Large terminals guarantee a simple connection of solar panels, battery and load. The Solsum E series controller works on PWM as a low loss series controller.


The Solsum E Series Controller Has Four Different Current For Your Choice:

Solsum 3.3E (3A)     Solsum 7.7E (7A)     Solsum 10.10E (10A)     Solsum 15.15E (15A)


---Solsum E series charge controllers are     ---Waterproof IP68 Industrial Level---
