EASUN POWER 12KW 48V Hybrid Inverter 150A Solar Charger Dual MPPT WIFI
12kW Hybrid Solar Inverter for Whole-Home Energy Storage
Built for high-power home energy systems, the IGrid-SGR-12KP-Wifi combines 12kW output, Dual MPPT solar input, parallel expansion, smart lithium battery control, TOU scheduling, CT-based energy monitoring, UPS backup, and 21-level protection with smart auto recovery.
12kW High Power for Confident Home Energy Use
With 12kW high-power output and 24,000VA peak power, this inverter is designed to support a wider range of household energy needs, from everyday appliances to higher-demand loads. It is suitable for home backup, solar self-consumption, off-grid applications, and larger battery storage systems.
Dual MPPT Solar Input with Parallel Expansion
Dual MPPT input makes solar installation more flexible for real homes. Solar panels installed on different roof sides, orientations, or sunlight conditions can be connected separately for better solar harvesting. For future expansion, up to 6 units can work in parallel for a larger power system.
Smarter Battery Control with BMS Communication and Auto Activation
BMS communication allows the inverter to exchange battery information with compatible lithium batteries, helping coordinate charging, discharging, and protection. The inverter also supports automatic lithium battery activation through PV or utility power, making battery recovery and daily operation more convenient.

TOU Scheduling with CT-Based Energy Monitoring
Through PC software, TOU scheduling allows you to set charging and discharging periods based on electricity tariffs. Charge the battery during lower-rate periods and use stored energy during peak-price hours. With CT support, the system can monitor home-grid power flow more accurately for smarter energy management.
UPS Backup Keeps Essential Loads Running
With a typical 10ms transfer time between bypass and inverter mode, the system can quickly switch to backup power when the grid becomes unstable or fails. This helps keep essential loads such as lighting, routers, refrigerators, computers, and other key devices running during outages.
21-Level Protection with Smart Auto Recovery
Built to protect the entire energy system, this 12kW inverter includes overload, short-circuit, battery over-voltage, battery low-voltage, PV reverse polarity, over-temperature, parallel system protection and more. For temporary faults such as overload or overheating, the system can pause operation, protect key components, and automatically resume once conditions return to safe levels.
FAQ
What is automatic lithium battery activation?
Automatic lithium battery activation means the inverter can help reactivate compatible lithium batteries through PV or utility power when the battery enters low-voltage or protection status. This makes battery recovery and daily operation more convenient.
What is TOU control?
TOU control allows you to set charging and discharging schedules through PC software. You can charge the battery during lower-cost electricity periods and use stored energy during peak-price hours, helping reduce reliance on expensive grid power.
What does CT support mean?
CT support allows the system to monitor power flow between the home and the grid. It helps improve energy management and can support functions such as load monitoring, self-consumption optimization, or export control depending on the system configuration.
What does 21-level protection include?
The inverter includes 21 built-in protections covering PV input, battery connection, AC input, AC output, bypass circuit, temperature control, communication, and parallel operation. These protections help reduce risks caused by overload, short circuit, over-voltage, low voltage, overheating, wiring errors, and system communication faults.
Can the inverter recover automatically after a fault?
For certain temporary faults, yes. For example, after overload protection, the inverter can try to restore output after a delay. If the internal temperature becomes too high, it will stop charging and discharging first, then resume automatically once the temperature returns to a safe range.
