0×C0 PV & Battery Off-grid
Grid power is cut, and the inverter supplies the load with a combination
of solar and battery power.
0×88 PV Charge Off-grid
Grid power is cut, and solar power is used to supply the load and
charge batteries simultaneously.
16. INVERTER MAINTENANCE
Electrical equipment must be properly maintained to increase longevity and consistency.
Follow the steps below to help prevent component damage/deterioration.
1. Inspect the inverter every month to confirm nothing covers the inverter heatsink. If it is
covered, shut down the inverter and clear the heat sink to restore proper cooling.
2. Inspect the inverter every 3 months to verify the operating parameters are normal, and there is
no abnormal heating or noise from any components in the system.
3. Inspect the inverter every 6 months to check for any damaged cables, accessories, or
terminals.
If unable to identify the source of any potential abnormal operations, contact the distributor’s
technical support team for additional information.
16.1 INVERTER START-UP AND SHUT DOWN PROCEDURE
After the inverter has been commissioned, use the following steps to properly start up and shut
down the inverter as needed.
Start-Up
Follow the steps outlined below to ensure proper start-up and shut down procedures to avoid
potential component damage.
1. Power on the batteries one at a time, starting with the master, in ≈5 second intervals. Close
the external battery breaker (if equipped).
2. Close (power on) the battery breaker on the master inverter.
3. Close (power on) the external PV isolator switch (if equipped). Close (power on) the PV switch
on the side of the unit.
4. If using AC input, close (power on) the external breaker between panel and inverter. Next,
close (power on) the GRID breaker on the front of the inverter.
5. Power on the inverter via the power switch on the side of the unit.
6. Close external AC Output breaker (if equipped) going to panel. Turn ON EPS Output (AC
Output) switch on side of unit to begin powering loads.
