This inverter can connect to following battery types: sealed lead acid battery, vented battery, gel
battery and lithium battery. The detailed installation and maintenance explanations of the
external battery pack are provided in the manual of the manufacturer’s external battery pack.
If using sealed lead acid battery, please set up the max. charging current according to the
formula below:
The maximum charging current = Battery capacity (Ah) x 0.2
For example, if you are using 300 Ah battery, then, maximum charging current is 300 x 0.2=60
(A). Please use at least 50Ah battery because the settable minimum value of charging current is
10A. If using AGM/Gel or other types of battery, please consult with installer for the details.
