20W Portable Solar System

1. PVES series is a set of DC power Supplying system, designed especially for the user for faraway and power shortage area.

2. Use the microprocessor and special control algorithm, realize the intelligent control.

3. Using simple operation. As long as open the main switch, it can be used.

4.Have discharging and over-discharge protected function. To prevent the battery from over- discharge affecting service life.

5. Scientific management of storage battery, when battery appears to be over discharge, it will charge battery to life the voltage as a supplementary maintenance. As for normal use, it will combine direct charge and floating charge, and a supplementary maintenance will be done every 7 days to avoid battery substation, therefore greatly extended the service life of the battery.

6. Charge circuit makes use of low MOS tandem control circuit, reducing nearly half circuit voltage losses than diode circuit.

7. LED visually displays the status of solar cell, batteries and working load. The user can know real time operating status.

8. Over-charge, over discharge, over load protection, unique electronic short circuit protection and protection against reverse polarity, which will improve system reliability and durability.

9. All control had adopted industial chip and precision components and it can work in cold, high temperature, moisture condition.
