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.
2.4.8 Audible Alarm
The inverter also gives audible alarms when the following situations occur.
2.4.9 FAN Operation
For M Series 5KW models, there are two DC fans.
The DC fans will just the fan speed in a linear proportion according to load and charger wattage.
It will slow down after 1 minute when the triggering condition disappears.
Allow at least 30CM of clearance around the inverter for air flow. Make sure that the air can circulate freely
around the unit.
Fan noise level <60db at a distance of 1 meter.
