Explanation
Beware of hot surface.
The inverter will become hot during operation. Avoid any contact
during operation.
Danger of high voltages.
Danger to life due to high voltages in the inverter!
Read the enclosed documentation.
CSA certified.
Danger to life due to high voltage.
There is residual voltage existing in the inverter after powering off,
which needs 5 minutes to discharge.
Wait 5 minutes before opening the upper lid or the DC lid.

A1-HYB-G2 series inverter is transformerless type without galvanic isolation. It is
designed and certified to fulfills the directives of ANSI/NFPA 70, NEC 690.5, UL 1741,
UL 1741 SA, IEEE 1547 and IEEE 1547.1. The inverter converts DC solar power to AC
power, then AC power to DC power and stores DC power into a battery bank.
With the device, you have acquired the system that can be used to power critical loads
during a grid outage by using a battery and be used to realize automatic transfer from
grid connection mode to off grid mode or from off grid mode to grid connection
model by using backup interface (BI). The inverter also has the ability to use power
generated from PV arrays along with other string inverters.
A1-HYB-G2 series
The A1-HYB-G2 series inverter manages battery and system energy.
PV Array
The PV array works in MPPT mode. For 3.8kW, 5.0kW and 6.0kW inverter, the number
of PV string is two. For 7.6kW inverter, the number of PV string is three.
RSD
The RSD provides an automatic disconnect of residential or small commercial PV
systems, fully compliant with the rapid shutdown requirements of National Electric Code
(NEC), ANSI/NFPA 70 Sections 690.12.
Battery (Optional)
The A1-HYB-G2 series inverter should be coupled with a high voltage battery. The
battery communicates with inverter via BMS and must be comply with the specification
of UL 1973.
Backup Interface (Optional)
The backup interface is used for realizing automatic transfer from grid connection mode
to off grid mode, or from off grid mode to grid connection mode.
Android/IOS APP
It is a powerful tool for monitoring, configuration or diagnosis.
SolaX Cloud
SolaX Cloud is an intelligent, multifunctional monitoring platform that can be accessed
either remotely or through a hard wired connection. Whether it’s for residential systems
or commercial PV systems, centralised management and monitoring of PV systems
saves time and money. With the SolaX Cloud, PV system operators and installers can
always view key and up to date data.
