Residential All-in-One Energy Storage System

iPower HES1-3K/3K6/4K6/5K/5K5/6K S2 HES1-1K5/3KL2

The all-new iPower HES1-3K/3K6/4K6/5K/5K5/6K S2 series is an integrated residential solar-storage-charging solution. Featuring a completely redesigned exterior that blends with home decor styles, it offers simple and convenient installation with a neat, aesthetically pleasing result after setup. Compatible with large photovoltaic modules, it can simultaneously charge batteries and feed power to the grid at rated capacity. With millisecond-level grid-tie/off-grid switching capability, the off-grid mode supports 2x power output for 10 seconds. Its integrated solar-storage-charging logic delivers greater economic benefits for users.
