Solar & Energy Storage: who this is for
03

How a storage battery is chosen

  1. 01

    Energy per day: what the loads use, in kWh.

  2. 02

    Days of storage: how many days without sun you need to cover.

  3. 03

    Voltage: set by the inverter.

  4. 04

    Communication: the protocol the inverter reads from the battery.

  5. 05

    Site: temperature, space and how the battery is mounted.

04

Documents and delivery

UN38.3, IEC 62133 and MSDS documents are available. Tell us the model and we confirm which documents cover it. Storage batteries are heavy goods and regulated for transport. We pack to the rules and ship worldwide from Shenzhen.

A simple sizing example

If a household uses 6 kWh a day and you want one day of storage, you need a battery with about 6 kWh of usable energy. Add margin for age, cold and unexpected loads. Then pick the voltage from the inverter. Your own numbers will differ, so send your loads and we size it.

Safety and installation

  • Install in a place with the temperature range allowed by the datasheet.
  • Use cables and fuses sized to the maximum current.
  • Follow the inverter maker's wiring guide.
  • Use a qualified installer where the rules require it.
