Products Description
The Solis 7K/8K/9K/10K Energy Storage Inverter is an excellent three-phase hybrid inverter specifically designed for large-scale residential energy storage systems. A key advantage of this model is its low-voltage (48V) battery compatibility allowing end users to utilize practically any of the leading battery brands on the market for their own unique flexibility.
This inverter range is designed for intelligence and durability. With several MPPTs, it is the perfect solution for complicated residential roofs with various directions to ensure you capture the maximum solar energy and generation possible . If a grid outage occurs, its lightning-fast switching time (as demonstrated in the S6-EH3P series, less than 10ms) allows you to run your critical home loads without delay, which gives incredible peace of mind . Additionally, its load management capabilities are second to none, can manage unbalanced three-phase loads and even half-wave loads, guaranteed for stable and reliable operation for all loads .
The S6-EH3P-L series was awarded the "Energy Storage Application Excellence Award" at a prominent industry trade show, showcasing its exceptional performance and reliability in practical applications.
When you select the Solis 7K/8K/9K/10K Energy Storage Inverter, you are investing into a future of energy independence, intelligent management and dependable reliability for your home.
