Inverter Operation - Helios RM-PSW5KVA Series Instruction Manual

Increasing your DC cable size will help improve the situation.
Our company recommends the following cables for optimum inverter performance
Model No
RM -PSW245KVA/E
RM -PSW485KVA/E
RM -PSW1105KVA/E
RM -PSW2205KVA/E
Also, use only high quality copper wiring and keep cable length short from 3-6 feet.

2-7 Inverter Operation:

To operate the power inverter, turn it on using the ON/OFF switch on the front panel. The
power inverter is now ready to deliver AC power to your loads.
If you are operating several loads from the power inverter, turn them on separately after the
inverter has been turned on.
This will ensure that the power inverter does not have to deliver the starting currents for all
the loads at once.
2-7-1 Controls and indicators:
The ON / OFF switch turns the control circuit in the power inverter on and off.
The Inverter operates from an input voltage ranging from :
20 to 32 VDC for 24V models
42 to 62VDC for 48V models
90 to 140VDC for 110V models.
180 to 275VDC for 220V models
The Inverter will indicate high and low DC voltage conditions as follows:

RM-PSW1105KVA/E
RM-PSW2205KVA/E
Note: Inverter will automatically start operating when input returns back to normal voltage
range, as per 2-7-1
