The inverter is built with automatic PV and utility power wakeup feature.
When the power switch is in power off, and qualified PV input, the PV charger will be activated, and the
rest part of the inverter will remain powered off.
In this mode, the utility power can only illuminate the LCD, it can’t charge batteries.
When the inverter shuts off due to low battery voltage, and the switch is kept on “on” position, the inverter
will use qualified utility power or PV power to charge batteries and wake up at “cold start voltage” to
discharge the battery to provide AC output.
If the inverter is set in SOL or SUB, the automatic wake up feature will charge battery close to “Utility to
Battery switch” voltage, and then cut off utility charger, switch to DC to AC model.
The M5000H-48BP inverters can be stacked up to 6 pcs to expand output power in 230Vac or create
230/400Vac three phase.
The M3048BP can be stacked up to 6 pcs to expand output power in 120Vac or create 120/208Vac three
phase.
When they are stacked, all the inverters will share the loads evenly. Each will be ready output full power
even the load is under nominal power, none of them will go into power saver mode.
This is designed to handle sudden loads fluctuations.
Note:
When there is more than one inverter paralleled in one phase, if the slave unit shut off, the rest inverters in
the system will continue operate.
If the master unit shuts off, all the rest inverters will shut off.
4 Maintenance & Troubleshooting
This troubleshooting guide contains information about how to troubleshoot possible error conditions while
