ABOUT Sumray + SOLIS SYSTEMS
Every Kilowatt Hour Usable. Every Kilowatt Delivered.
The Sumray SR-LV14G low-voltage modular battery paired with a Solis Solarator hybrid inverter is built for Australian homes that actually use their power. Stacked storage from 14 kWh to 56 kWh, 100% depth of discharge, and an 8kW single-phase inverter that can run your ducted air conditioning, your hot water and your backup circuits at the same time.
Most single-phase battery systems on the market top out at 5 or 6 kW. This one does not. That difference decides whether your battery carries your house through a summer afternoon, or watches while you buy power at peak rates.
Sumray SR-LV14G Modular Battery
๐ 100% Usable Capacity
Rated energy and usable energy are the same number. A 13.92 kWh module gives you 13.92 kWh. Full depth of discharge means you are not paying for storage you are never allowed to touch.
๐ Built For Australian Coastlines
IP66 rated, salt-spray tested and C4 corrosion protected. Suitable for genuinely harsh outdoor environments, from coastal Sydney to regional heat.
๐ฅ Aerosol Fire Suppression + Module-Level MCB
Every module carries its own circuit breaker and the pack is protected by an aerosol suppression system. Isolation and protection at the module level, not just the pack.
๐ฆ Stack From 14 kWh To 56 kWh
Start at 13.92 kWh and stack to 55.68 kWh in a single tower, then parallel up to four towers. Add modules as your household load grows. 10,000+ cycle design life.
Available Systems & Pricing
Add extra 14kWh for $3000 (42kWh total power)

Why The 8kW Inverter Matters
From 1 July 2026, the federal Solar Sharer Offer requires retailers to make a plan available with three hours of free electricity every day. In NSW and south east Queensland that window runs 11am to 2pm, and you can draw up to 24 kWh of free power inside it.
An 8kW inverter can take 24 kWh in three hours. A 6kW inverter takes 18 kWh. A 5kW inverter takes 15 kWh.
๏ปฟThat is up to 9 kWh of free electricity a day that a smaller system physically cannot accept. Pair the 8kW Solis with a 27.84 kWh Sumray battery and you have both the pipe and the tank to take the lot.
