Chinese energy storage solutions company Solinteg has released a new series of residential solar storage systems. The IntegOne HSH line integrates a single-phase hybrid inverter with a modular battery design. Depending on the model, the system has an AC power of 3 kW, 3.6 kW, 4.2 kW, 4.6 kW, 5 kW or 6 kW. Each battery has a capacity of 5 kWh and up to two batteries can be connected to each system.
“The system is designed with scalability in mind, allowing homeowners to expand their energy storage configuration by connecting up to ten systems in parallel,” the company said. “This flexibility makes it easy to adapt to growing energy needs, providing a tailor-made and future-proof solution for the different energy needs of households.”
The system’s batteries are EBA-B5K1 batteries with a lithium iron phosphate structure (LiFePO4). They have a lifespan of 6,000 cycles and an operating temperature of -20 C to 55 C. The inverter can handle a PV input current of 20 A and a voltage of 580 V. Depending on the model, it has one or two Maximum Power Point Trackers (MPPT).
“The system guarantees uninterrupted power supply with a switching time from grid to off-grid of less than 10 milliseconds,” the company added. “This ultra-fast transition ensures continuous energy availability during power outages, increasing energy security and ensuring the safety of household electrical appliances.”
Each module is 1.125 meters wide, 40 cm high and 19.7 cm deep. The system weighs 63 kg or 65 kg depending on the model, operates within a temperature range of -30 C to 60 C and keeps the noise level below 25 dB. The maximum efficiency reaches 97.6%.
