Page 20
6) Plug in load to inverter standalone output, inverter will feed-in the residual power to Grid to
balance the power consumption of load (If the residual power is more than load, inverter would
reduce the input power to make the net power to Grid as zero).
6.2 Operation Modes
Self-consumption (On-Grid) Mode
In this mode, the inverter convers PV power to charging battery and/or to balance the load power
consumption; Whenever the DC voltage is lower than 25Vdc, the inverter will work in waiting state and
attempt to connect the grid by 5mins for <25Vdc and 30s for <16Vdc. In waiting state the inverter
continuously monitors the internal system. Grid bypasses power to load directly.
Note: The inverter starts up automatically when DC power from the PV panel is sufficient.
Off Grid Mode
In this mode, whenever the PV or Battery has sufficient power, the inverter convers PV and/or battery
power to loads when Grid power is no available.
Fault Mode
The internal intelligent controller can continuously monitor and adjust the system state. If inverter finds
any fault conditions, inverter would shutdown immediately
Bypass Mode
When no PV power during On Grid operation, inverter off internal switch but keep bypass relay on to
continuously supply loads power from Grid directly.
Charger Mode
If user doesn’t want On-Grid, bypass or Off-Grid operation, wants all PV power to charge battery. Either one
of below ways can make inverter stay in charger mode.
- Disconnect Grid O/P and Standalone, power on PV power.
- Press and hold button for 3s during operation (inverter would back to On-Grid operation after PV
power off and on) if Grid is available.
Sleeping Mode
User can off inverter by press and hold the button for 3s during inverter operation. In this mode, inverter
off all LEDs to save energy but keep monitoring the internal system for quickly going back to normal
operation. When PV power comes back, inverter will enter charger mode automatically. When PV power is
gone, inverter will enter shutdown mode.
PV >27V and <50V
User Manual 14 Hybrid CPSHB300ETR
Page 21
Shutdown Mode
Inverter automatically stop running during no PV power and low battery. In shutdown mode the inverters
take no power from panel and battery. If Grid is available, the inner charger would continuously charge
battery but without any LED indicator. If user wants to check the capacity of battery in this mode, can press
the button and see the battery LED color.
De-rating mode
When temperature high or PV voltage >38Vdc, the inverter will de-rate its output power.
6.3 Charge Current Setting
Risk of damage to the inverter
Adjust the charge current according the total Ah value of battery and don’t
more than 0.3C (ex. S
et 2Amax for 9Ah, 6Amax for 20Ah). Larger charge
current to lower capacity battery can reduce the life of battery.
User can set the charge current as 1/2/3/5/7/9A (default is 1A).
Note: The charger power comes from PV. Larger charge current would reduce the feeding power to Grid
and/or loads.
Procedure for changing charge current,
Press and hold the button. 3s later, inverter shutdown and all LEDs are red Another 3s later, all LEDs
are green
Another 3s later, BAT LED is blinking with green and the other LEDs are orange, release the
