Step4:
Purchase an uninterruptible power supply (UPS). This is
required
if you have ANY sets with Battery Commander. If you do NOT
have any sets with Battery Commander, a UPS is optional but
recommended.
A UPS is a device with a built-in battery to supply AC power when
grid power goes down. A rating of 400VA or larger is
recommended. UPS is not included.

Plug the AC cord from Solar Regulator into any AC outlet. If you’re
using a UPS, plug the AC cord into the Battery Backup receptacle

outage and check if Solar Regulator LED indicator lights remains
on.

Download Legion Solar app for iOS/Android and follow the
