12V 24V Solar Controller PV Solar Charge Controller With LCD Display, 10A, 20A, 30A

-Supports battery types:
-B1=lead-acid batteries
-B2=lithium battery
-B3=lithium iron phosphate batteries

-Safe use recommendations:
1. The controller defaults to 12V/24V auto-adaptation, when installing for the first time, please make sure to connect the battery first and ensure that the battery has enough voltage so that the controller can recognize it as the correct battery type
2. Install the controller as close to the battery as possible to avoid the voltage drop caused by long wires, which will affect the normal voltage judgment
3. This controller is only applicable to B1 lead-acid batteries, B2 lithium batteries, B3 lithium iron phosphate batteries
4. This controller can only use photovoltaic panels as charging power, please do not use DC or other power sources as charging power
5. The controller will be hot when running, please pay attention to install the controller on a flat, well-ventilated surface
