Depth Of Discharge
100%
This means that you can use all of the energy stored in your battery. Some batteries will restrict the depth of as their batteries can’t recharge if they are totally empty.
Water Ingress Rating
IP66
What does that mean? Well, it means your battery and inverter are weatherproof. So, you can place your Sigenergy products outside if you don’t want them inside.
Warranty
10 Years
Most solar batteries will be able to charge and discharge about 6000 times – which works out to about twice a day for 10 years. Hence the warranty.
Storage Temp Range
-20° to 60°
Your Sigenergy battery will still be able to store electricity efficiently between these temperatures. We’re not sure the rest of the UK would be happy at 60 °C though!
