INVG Series
Commercial Solar Inverter.
Built for Commercial and Industrial Solar
Wide DC Input
Compatible with Modern PV Systems
Selected INVG models support a maximum DC input voltage of up to 1100 V and a broad MPPT operating range. This supports longer PV strings and provides greater flexibility when designing commercial and industrial solar systems.
High Efficiency
Convert More Solar into Usable Power
With maximum conversion efficiency of up to 98.7%, INVG reduces energy loss during DC-to-AC conversion. High conversion efficiency helps improve the long-term energy yield and financial performance of commercial solar projects.
1.5 DC/AC Ratio
Support Larger PV Arrays
INVG supports a DC-to-AC ratio of up to 1.5, allowing the connected solar array capacity to exceed the inverter’s nominal AC output. This gives system designers greater flexibility to improve inverter utilisation during periods of lower solar irradiance.
IP66 Protection
Reliable Outdoor Operation
The IP66 enclosure protects the inverter against dust and powerful water jets, supporting installation in demanding commercial and industrial environments. Selected models also operate across temperature ranges as low as -30°C and as high as +60°C, with power derating under specified high-temperature conditions.

More Than a Standalone DC Charger
EVD002 can operate as part of a complete energy and mobility solution connecting renewable generation, energy storage, charging infrastructure, electric vehicles and intelligent operations.
Lower Energy Costs
Combine smart charging with solar generation, battery storage and time-based energy strategies to reduce expensive peak-period grid consumption.
Higher Charging Availability
Connected monitoring, multiple protection functions and remote service tools help operators identify issues and maintain reliable day-to-day charging.
Flexible Site Deployment
The compact wall-mounted or pedestal design makes it easier to add DC charging to commercial sites with limited space or different parking layouts.
Scalable Operations
OCPP connectivity allows EVD002 chargers to be managed through a central platform and expanded as the charging network or fleet grows.

FAQ
What is the INVG Series?
INVG is a family of three-phase on-grid solar inverters for commercial and industrial PV systems.
The series covers nominal output power ratings from 30 to 125 kW.
Is INVG a hybrid inverter?
No. The INVG models are on-grid solar inverters.
They convert DC electricity from solar panels into AC electricity for use by the facility or export to the grid.
For battery storage applications, a compatible energy storage inverter or hybrid system is required.
Which INVG model should I choose?
The correct model depends on:
- Total PV array capacity
- Grid voltage
- Number and orientation of solar strings
- Maximum module current
- Available installation space
- Local grid requirements
- Future project expansion
A project-specific electrical design is recommended before model selection.
How many MPPTs does INVG support?
The number varies by model.
The INVG range provides between three and nine MPPT trackers, except for some 50–80 kW configurations listed with different MPPT arrangements.
The exact number should be checked against the selected model.应将确切数字与所选型号进行核对。
What is the benefit of multiple MPPTs?
Multiple MPPTs allow groups of solar panels with different orientations, shading or electrical characteristics to be controlled independently.
This helps reduce mismatch losses and improves solar-system design flexibility.
What does a DC/AC ratio of 1.5 mean?
It means the connected solar-panel capacity can be designed at up to 1.5 times the inverter’s nominal AC power, subject to model limits and project conditions.
For example, a 50 kW inverter may support a larger PV array so that the inverter operates closer to full output for more hours of the day.
How can the inverter be monitored?
Communication options vary by model and may include RS485, Wi-Fi, Ethernet, PLC and optional 4G.
Some high-power models also support Bluetooth and App-based access.部分高功率型号还支持蓝牙和基于应用程序的访问。
Can INVG work with EV chargers?
Yes, at the site-system level.
Solar electricity converted by the INVG inverter can be used by building loads or EV charging infrastructure. An EMS can coordinate solar generation, site demand, storage and charging.
