Matching Inverters with Solar Controllers？

In off-grid photovoltaic systems, how should inverters and controllers be paired? Off-grid systems must follow the connection sequence: “solar panels → controller → battery → inverter → load.” The matching principles are:

The controller's voltage must match the battery voltage;

Does the solar controller require daily maintenance?

Regularly inspect the terminal connections to ensure they are secure, free from oxidation, and not loose;

Clean dust from the controller's surface to maintain ventilation and heat dissipation;

Periodically verify the controller's protection voltage parameters to ensure compatibility with the battery type.
