BOSYTRO 80A Solar Charge Controller with DC

Solar Controller User Manual

Safe use Advice

1. The controller can only be used for photovoltaic panels charging. Do not use DC or other power sources as charging sources.
2. The controller is only suitable for all kinds of lead-acid batteries (including openings, seals, gels, etc.). Do not use it for other batteries such as lithium batteries or nickel metal hydride batteries.
3. Install the controller close to the battery to avoid voltage drop caused by too long wires and affect normal voltage identification.
4. The controller automatically identifies 12V/24V battery. When installing for the first time, ensure that the battery has enough voltage so that the controller can identify the correct battery type.
5. Install the controller on a flat, well-ventilated surface.

Technical reference

• Equalization:

  • Sealed Battery: 14.4V
  • Gel Battery: 14.2V
  • Flood Battery : 14.6V

Note : Connect the charge controller to the battery first, then the solar panel, and finally the load. Connect in strict order to avoid damaging the controller. The disassembly sequence should be opposite to the wiring sequence

Specifications

• 12V battery and 18V solar panel
• 24V battery with 36V solar panel
• Not applicable:
• Lithium battery, NiMH battery

Note:
Charge controller should connect battery first, then solar panel, finally the load!Please connect in strict order, otherwise controller may damaged, disassembly sequence is opposite to the wiring sequence.
