Recommendations for safe use
1. This controller is suitable for three types of batteries, including lead-acid batteries (12V/24V automatic identification) and lithium-ion batteries (three 11.1V lithium batteries in series); Lithium iron phosphate battery (4-string 12.8V) should not be used for other batteries.
Battery type description: B1 is a lead-acid battery (12V/24V automatic identification); B2 is a lithium-ion battery (3 strings of 11.1V lithium-ion batteries); B3 is a Lithium iron phosphate battery (4 strings of 12.8V), and the default factory setting is B2.
2. Install the controller as close as possible to the battery to avoid voltage drop caused by excessively long wires, and judge the normal voltage according to the background sound.
3. When installing for the first time, please set the battery type according to the battery type and ensure that the battery has sufficient voltage so that the controller can recognize it as the correct battery type.
4. This controller can only use photovoltaic panels as the charging source. Do not use DC or other power sources as the charging source.
5. This controller may generate heat during operation. Please pay attention to installing the controller on a flat and well ventilated surface.
