Company Info
JinkoSolar has been involved in battery storage for some years; originally focusing on C&I and utility-scale products up to 1MWh in capacity. In July 2022, the company launched its Suntank home battery in Australia. Jinko has been a dominant player in solar panel manufacturing, but it remains to be seen how their move into home energy storage will pan out.
About The JinkoSolar Suntank
The JinkoSolar tank is a modular system using JKS-B51 modules, which each have a nominal capacity of 2.56kWh and usable capacity of 2.3kWh. Up to ten modules can be stacked for a maximum capacity of 25.64kWh (23.04kWh usable).
A single module has a maximum charging/discharging power of 2.45kW, but by using three modules or more, the maximum is boosted to 5.63kW. The modules are based on LiFePO4 chemistry, which is widely regarded as one of the safest lithium-ion energy storage chemistries available for home applications. A module measures 650 x 260 x 185mm and weighs 28 kilograms. A full stack of 10 modules would be 1.81 metres high.
The Suntank offers both AC and DC-coupling methods, but the only hybrid inverter it is compatible with is Jinko's JKS-5HLVS-ABI.
Among Suntank's other features is backup supply to an emergency circuit - which could be a pretty handy thing to have for providing power to critical loads in a blackout situation. Operating in this mode, up to 4kW of power is available and switchover time is under 10 milliseconds.
The operating temperature range for Suntank is -10°C ~ 50°C and the battery charging temperature range is 0°C ~ 50°C. The ingress rating is IP65, meaning it can be installed outside. As at late 2024, Suntank is listed on the Clean Energy Council's approved batteries list.
Warranty Information
A SolarQuotes analysis of the battery warranty in June 2023 found while it’s possible the battery could be good, the warranty was quite poor. Fortunately, the article caught Jinko's attention and the company considerably improved the warranty soon after.
The Suntank is now accompanied by a 10 year warranty (if connected to the internet, 5 years if it isn't). The battery modules are warranted for a minimum capacity of 60% by the end of the period, or 3,050kWh of stored energy per kWh of usable capacity (whichever comes first).
