2 Installation
2.1 Attentions
Be very careful when installing the batteries. Please wear eye protection when installing the open-type
lead-acid battery and rinse with clean water in time for battery acid contact.
Keep the battery away from any metal objects, which may cause a battery short circuit.
Acid gas may be generated when the battery is charged. Ensure that the surrounding environment is
well ventilated.
Avoid direct sunlight and rain infiltration when installing it outdoor.
Loose power connections and corroded wires may produce high heat that can melt wire insulation,
burn surrounding materials, or even cause a fire. Ensure tight connections and secure cables with
clamps to prevent them from swaying while moving the inverter.
Only charge the lead-acid and lithium-ion batteries within the control range of this controller.
The battery connector may be wired to another battery or a bank of batteries. The following instructions
refer to a singular battery. Still, it is implied that the battery connection can be made to either one
battery or a group of batteries in a battery bank.
Select the system cables according to 5A/mm
2.2 Requirements for the PV array
Serial connection (string) of PV modules
As the core component of the solar system, the controller needs to suit various PV modules and
maximize solar energy conversion into electricity. According to the open-circuit voltage (VOC) and the
maximum power point voltage (VMPP) of the MPPT controller, the serial connection of PV modules
suitable for different controllers can be calculated. The below table is for reference only.
