12/24v 5A/10A /15A /20A /30A  solar charge controller

Product overview

1. Use single-chip microcomputer as the core of the whole control system, which makes the controller has the advantages of intelligent, strong adaptability, reliable function etc.

2. Use 03 version optimized design scheme, which can improve system efficiency and prolong the life span the battery.

3. Use SMT chip production technology, industrial class chip, advanced technology, quality assurance.

4. With over charge, over discharge, electronic short circuit, overload and reverse polarity protection.

5. Use series connection PWM circuit, it is 3%-6% more effective than non-PWM circuit when charging.

6. With LED to show the current battery state, it is easy for the user to know the working condition of the controller right now.

7. Use industrial grade chip, it can work properly under environment such as cold, high temperature, humid.

8. Delicate shell design and compact circuit, the whole controller does not occupy too much space.

9. Use internal integration precision resistors and other components in order to improve the precision of controller parameters.

10. With 12V DC (750mA) and 5V USB (500mA) output , which can charge for mobile phone and other small appliance.

Protection

1.  PV Reverse Polarity Protection

Fully protection against PV reverse polarity, no damage to the controller will result. Correct the miswire to resume normal operation.

2. BatteryReverse Polarity Protection

Fully protection against battery reverse polarity, no damage to the controller will result. Correct the miswire to resume normal operation.

3. BatteryOvercharge Protection

When charging, once the battery voltage reaches the preset voltage, the controller will automatically cut off the charging circuit.

4. BatteryDischarge Protection

When discharging, once the battery voltage reaches the preset voltage, the controller will automatically cut off the discharging circuit.

5. Output Over Current Protection

The current output, the controller will cut off the output circuit when the current 1.5 times exceeds the rated current.

6. Load Short Circuit Protection
