Fusing and Setting
-Fusing position
The requirement to protect photovoltaic systems from overcurrent
conditions is defined in Article 690.9(A) of the NEC. Fuses are required
to protect cables and PV modules from line-line, line-ground and
mismatch faults. The sole purpose is to prevent fire and safely open a
faulted circuit if an overcurrent event were to occur. However, there are
some situations where fusing is not required and is defined by the
following:
Two Strings in Parallel (fusing not required)
So no need to fuse the PV array you built, or the connection between it
and controller.

(Note: the inverter only works when 24V battery bank connected)
-Inverter to appliances
Before booting the inverter, the AC OUT ports should be wired with the
home socket or appliances first.
-Turn on the inverter
When all wirings are done, check if the battery type switcher is at Li-ion,
since it’s connected with lithium battery bank. The final step is to boot
the hybrid inverter by pressing the switch on its bottom.
