in a safe place for future reference, along with the completed warranty card,
purchase receipt and carton. If applicable, pass these instructions on to the
next owner of the appliance.
Always follow basic safety precautions and accident prevention
measures when using an electrical appliance, including the following:
WARNING: Electric shock hazard - professional installation only!
• This appliance must be professionally installed to an appropriately earthed
wiring system by a licensed installer, following the instructions in this manual.
• Ensure to make these instructions available to the installer. Failure to install
the appliance correctly could invalidate any warranty or liability claims.
• Alterations to the domestic wiring system must only be made by a qualified
electrician. Failure to follow this advice may result in electric shock or death.

Introduction
Inverter Introduction
These hybrid inverters are designed to increase energy independence for
homeowners. Energy management is based on time-of-use and demand charge rate
structures, which significantly reduces the amount of energy purchased from the
public grid and optimize self-consumption.
Operation Modes
Self-Use Mode
The Self-Use mode is designed for areas with low feed-in tariff and high electricity
prices. The energy produced by the PV system is used to optimize self-consumption
needs. The excess energy is used to recharge the batteries, any remaining excess is
then exported to the grid.

Note:
Warning:
However if an external residual current device (RCD) (type B is recommended) is mandatory,
the switch must be triggered at a residual current of 300 mA (recommended). RCD of other
specifications can also be used according to local standard.
A type B RCD is required
on the EPS port of the inverter.

Note: Advanced Settings
• When you select 0 W under P_Feed menu, the inverter will export zero energy to
the grid.
• When you select xx W under P_Feed menu, the inverter will export customized
energy to the grid.
Time of Use Mode
The Time of Use mode is designed to reward customers who do their part to reduce
demand on the electric grid, particularly during peak usage periods. This allows you
to use most of your electricity from PV energy and during off-peak time periods, which
could significantly lower your monthly bill.

PV Connection
This series of hybrid inverter has one/two MPPT channels, can be connected with
one/two strings of PV panels. Please make sure below requirements are followed
before connecting PV panels and strings to the inverter:
• The open-circuits voltage and short-circuit current of PV string should not exceed
the reasonable range of inverters.
• The isolation resistance between PV string and ground should exceed 300 kΩ.
• The polarity of PV strings are correct.
• Use the DC plugs in the accessory.
• The lightning protector should be equipped between PV string and inverter.
• Disconnect all of the PV (DC) switches during wiring.
WARNING!
The DC voltage may be fatally high - please comply with electrical safety warnings
when connecting. Please make sure the correct polarity of the cable is connected
with inverter, otherwise the inverter could be damaged.
