The 3 phase 12KW hybrid Solar Inverter (SUN-12KS48P3) is designed for European and international markets, integrating PV charging, battery storage, grid feed-in, and off-grid backup capabilities into a single unit.
Its unique design allows for a 200% PV oversizing ratio, enabling the connection of more PV modules to ensure battery charging and meet off-grid load demands even in low-light conditions.
It features a built-in intelligent BMS communication interface for seamless integration with mainstream lithium battery systems (such as Pylontech and BYD). The product complies with multiple international grid-connection standards, including NB/T32004, IEC62109, and EN50549-1, making it suitable for factories, farms, office buildings, and remote areas requiring three-phase power.
With a maximum charge/discharge current of 250A and off-grid peak power supporting 200% overload (for 15 seconds), it can handle surge loads from motors and compressors. It boasts a peak efficiency of 98%, supports generator input and remote monitoring, and provides stable, reliable energy conversion for three-phase loads.

Dual MPPT channels (max. input current 36A/18A) with a wide operating voltage range and low start-up voltage; perfectly compatible with high-power 18A PV modules to enhance power generation efficiency in low-light conditions.
Maximum charge/discharge current of up to 250A, supporting rapid charging and discharging to meet high energy throughput requirements. Rated battery voltage of 48V; compatible with both lithium and lead-acid batteries. 3. 200% Off-Grid Overload Capacity
In off-grid mode, peak power can reach 200% of the rated power for 15 seconds, easily starting inductive loads such as three-phase motors, air conditioners, and water pumps.
The 3 phase 12KW hybrid Solar Inverter supports grid-tied feed-in and independent off-grid operation, with configurable modes (self-consumption, peak-valley arbitrage, backup power priority).
Supports generator integration; features built-in anti-backflow and anti-islanding protection. Communicates with the BMS via RS485, CAN, and other interfaces for real-time battery status monitoring.
Includes PV reverse polarity protection, insulation impedance detection, leakage current detection, and output over-voltage/over-current/short-circuit protection, ensuring a high level of safety.
Suitable for small factories, commercial complexes, and office buildings; utilizes peak-valley electricity price differences to reduce costs while serving as backup power to ensure operational continuity.
Provides stable three-phase power for farms, mining sites, and islands without grid coverage by integrating with PV arrays and battery packs.
Ideal for homes or estates with three-phase PV systems; prioritizes the use of solar power, with excess energy stored in batteries or fed into the grid.
Automatically starts a generator to supplement power during prolonged periods of overcast or rainy weather, ensuring uninterrupted, round-the-clock power supply for off-grid systems.

Yes. The SUN-12KS48P3 is a three-phase inverter with a rated output voltage of 230/400V (50/60Hz), complying with low-voltage grid standards in Europe and most other countries.
20A at 230V corresponds to approximately 4.6kW, yet the table lists an off-grid rated power of 1200W (likely a typo for 12kW). In reality, the off-grid rated power of the 12KS48P3 is 12kW, corresponding to a current of approximately 30A (per phase). Please refer to the nameplate or the latest manual for accurate specifications.
3 phase 12KW hybrid Solar Inverter features built-in RS485 and CAN interfaces and supports mainstream lithium battery protocols (such as Pylontech, BYD, LG, AlphaESS, etc.), with compatibility achieved through BMS parameter configuration.
