INTRODUCTION
The VTAC Hybrid Solar Inverter series hybrid inverters are designed to increase energy
independence for homeowners. Energy management 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.
OPERATION MODES
Self-Use
The Self-Use mode is for the regions 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: Advance Setting
• 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.

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 off-peak time periods, and you could significantly lower your
monthly bill.

Mounting Location
The inverters are designed for indoor and outdoor installation (IP65), to increase the
safety, performance and lifespan of the inverter, please select the mounting location
carefully based on the following 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

PV CONNECTION
The VT-66036103 series hybrid inverter has two MPPT channels, can be connected with
two strings of PV panels. Please make sure below requirements are followed before
connecting PV panels and strings to the inverter:
• The open-circuit voltage and short-circuit current of PV string should not exceed the
reasonable range of the 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) switch during wiring.
Warning:
The fatal high voltage may on the DC side, please comply with electric

NOTE:
STEP 1:
PLEASE FOLLOW STEPS FOR AC CONNECTION
Qualified electrician will be required for the wiring.
The AC terminal contains “GRID” and “EPS”, GRID for load, and EPS for emergency
load.
Before connecting, a separate AC breaker between individual inverter and AC input
power is necessary. This will ensure the inverter be securely disconnected during
maintenance and fully protected from current of AC input.
An extra AC breaker is needed for On-Grid connection to be isolated from grid when
necessary. Below are requirements for the On-Grid AC-breaker.
• Connect DC protector or breaker first before connecting.
• Remove insulation sleeve 11mm(0.5 inch) length, unscrew the bolts, insert the AC
input wires according to polarities indicated on the terminal block and tighten the
terminal screws.

All these faults will be
detected or reported by
battery BMS.
• If specific fault high temperature or low
temperature, then should change battery
installed environment temperature.
• Restart battery, maybe can working as
normal.
• If this fault occurs continuously and
frequently, please ask help for local
distributors.
Battery temperature
sensor abnormal
• Check battery temperature sensor and
connected wires damage or not , then
rectification or change new one.
Battery voltage over or
under
• Check inverters connected battery lines
and connectors broken or loose connect.
• Carry out rectification if broken or
loose.
• Checking battery voltage is abnormal
or not, then maintenance or change new
battery.
B04 PcsBatReversedFault
Bat. (+) and Bat. (-) are
reversed.
• Check Bat.(+) and Bat.(-)connect
reversed or not.
• Make correction If reversed.
B05 PcsBatConnectFault
Battery wires loose
• Check battery wires and connectors
damage or loose connect.
• Carry out rectification if break.
B06 PcsBatComFault
Battery communication

• Check battery side communication
wires damage or loose connect, and
then carry out rectification.
• Check battery is off or other abnormal,
then Mastertenance battery or change
