Ensure the DC cables are connected tightly, securely and correctly.
Measure the DC cable using the multimeter to avoid reverse polarity connection. Also, the
voltage should be within the permissible range.
The two input strings per MPPT should be of the same type, the same number of modules, the
same tilt and angle to ensure the best efficiency.
6.6 Connecting the Battery Cable
In a single inverter system, do not connect the same battery pack to multiple inverters, which
may cause inverter damage.
It is forbidden to connect loads between the inverter and batteries.
When connecting battery cables, use insulated tools to prevent accidental electric shock or
short circuit to the batteries.
Ensure that the open circuit voltage of the battery is within the permissible range of the
inverter.
Install a DC breaker between the inverter and the battery in compliance with local local laws
and regulations.
