tions during installation, operation and maintenance.
SAFETY PRECAUTIONS
1. All work on the inverter must be carried out by qualified electricians.
2. The PV panels and inverter must be connected to the ground.
3. Do not touch the inverter cover until 5 minutes aer disconnecting both DC and AC power supply.
4. Do not touch the inverter enclosure when operating, keep away from materials that may be aected
by high temperatures.
5. Please ensure that the used device and any relevant accessories are disposed of in accordance with appli-
cable regulations.
6. VTAC inverter should be placed upwards and handled with care in delivery. Pay attention to waterproof. Do
not expose the inverter directly to water, rain, snow or spray.
7. Alternative uses, modifications to the inverter not recommended. The warranty can become void if the inverter
was tampered with or if the installation is not in accordance with the relevant installation instructions.
SYMBOL EXPLANATION
Danger of electric shock
The inverter contains fatal DC and AC power. All work on the inverter must be
carried out by qualified personnel only.
Beware of hot surface
The inverter’s housing may reach uncomfortably hot 60°C (140°F) under high
power operation. Do not touch the inverter enclosure when operation.
Residual power discharge
Do not open the inverter cover until 5 minutes aer disconnection both
DC and AC power supply.
Important notes

INTRODUCTION
OPERATION MODES
Basic Instruction
Self-Use
Note: Advance Setting
The VTAC hybrid inverters are designed to increase energy independence for homeowners. Energy
manag ment is based on time-of-use and demand charge rate structures, significantly reduce the
amount of energy purchased from the public grid and optimize self-consumption.
The Self-Use mode is for the regions with low feed-in tari 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 batte ies, any remaining excess is then exported to the grid.
When select 0 W under P_Feed menu, the inverter will export zero energy to the grid.
When select xx W under P_Feed menu, the inverter will export customized energy to the grid.

AC Charge 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. Use most of your electricity from PV energy
and during o-peak time periods, and you could significantly lower your monthly bill.
Note:
Aer select AC charge, when PV have no
sucient power, AC will also charge the
battery.

The Selling First mode is suitable for the regions with high feed-in tari.
When the grid fails, the system will automatically switch to Back-Up mode. The back-up loads can
be supplied by both PV and battery energy.
Energy flow: PV and Battery → Load

Mounting Location
The inverters are designed for indoor and outdoor installation (IP65), to increase the safety, perfo
mance and lifespan of the inverter, please select the mounting location carefully based on the fol-
lowing rules:
• The inverter should be installed on a solid surface, far from flammable or corrosion materials,
where is suitable for inverter’s weight and dimensions.
• The ambient temperature should be within -25°C ~ 60°C (between -13 °F and 140°F).
• The installation of inverter should be protected under shelter. Do not expose the inverter to direct
sunlight, water, rain, snow, spray lightning, etc.
• The inverter should be installed vertically on the wall, or lean back on plane with a limited tilted
angle. Please refer to below picture.
