Common Questions
Click a question below to reveal the answer.
What is the difference between the Solis 6kW and 10kW PLUS hybrid inverters?
Both are in the S6 PLUS single-phase LV hybrid range with the same feature set. The 6 kW has 9.6 kW max usable PV input (vs higher on the 10 kW), 135 A max battery current (vs 190 A), and smaller dimensions at 335 x 560 x 253 mm (23.5 kg). Both support 48 V batteries, less than 10 ms backup switching, 200% overload, and up to 6 units in parallel.
Can I keep my existing grid-tied solar inverter?
Yes. The S6 PLUS supports AC coupling, allowing connection to an existing PV grid-tied inverter for export control and off-grid use.
Does this inverter come with a battery cable?
No. A DC cable for connecting to battery storage is not included. The inverter comes with a CT clamp only.
Does this inverter support backup power?
Yes. It provides backup switching in less than 10 ms with 200% overload for 10 seconds, and smart load management for critical load prioritisation.
Is this inverter VPP-ready?
Yes. The S6 PLUS features AI-powered energy management and is VPP-ready, enabling potential revenue from grid services participation.
