30A 12V 24V Lithium Lead Acid Solar Charge Controller PWM PV Controller With LCD Display

-Supports battery type (factory setting defaults to B2):
-B1=Lead-acid battery 12V/24V (automatic recognition)
-B2=Lithium ion battery (3 strings of 3.7V=11.1V lithium battery)
-B3=Lithium iron phosphate battery (4 strings of 3.2V=12.8V)

-Safe use recommendations:
1. This controller is suitable for 3 kinds of batteries, lead-acid batteries (12V/24V battery automatic identification), lithium-ion batteries, lithium iron phosphate batteries, please do not use in other batteries
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. When installing for the first time, please set the battery type according to the battery type, and make sure the battery has enough voltage so that the controller can recognize the correct battery type
4. This controller can only use photovoltaic panels as a charging source, please do not use DC or other power sources as a charging source
5. The controller will be hot when running, please pay attention to install the controller on a flat, well-ventilated surface
