Low-Frequency Off-Grid Solar Inverter

JVM600048SP: A Low-Frequency Off-Grid Solar Inverter with 120V/240V Split Phase Output

The JVM600048SP is a low-frequency off-grid solar inverter that combines a 250VDC MPPT solar charge controller and a 6KW inverter in one device. It features a low-frequency transformer that ensures high conversion efficiency and low power consumption. It also supports WiFi/GPRS remote monitoring, AC coupling function, and parallel operation up to 6 units. With its split phase output, it can deliver 120V and 240V AC power simultaneously, and provide up to 12KW of continuous power in AC bypass mode and inverter mode.

1. Rated power: 6KW.
2. Built-in MPPT solar charge controller: 250VDC.
3. Low-frequency transformer: improves stability and reliability.
4. High conversion efficiency: up to 93.5%.
5. Low power consumption: less than 1.5% when no load.
6. WiFi/GPRS remote monitoring: allows you to check the system status and performance from anywhere.
7. AC coupling function: enables you to connect to the grid or a generator for backup power.
8. Split phase output: delivers 120V and 240V AC power at the same time.
9. AC bypass mode + inverter mode: jointly outputs up to 12KW of continuous power.
10. Parallel operation: supports up to 6 units for capacity expansion.

I have pleasant experience buying from Shenzhen Suns. They shipped quickly, and very responsive and provided accurate updates. Shipment to Malaysia reaches in just a few weeks with a door to door delivery. Equipment work great, as can be seen from the photos, in the midst of installation and already in operation. The sales representative (Amy) has provided good knowledge and helpful to guide me to make the purchase correctly. Thank you Amy and thank you Shenzhen Suns and this company is highly recommended!
