Deye BOS-G at a glance
Deye BOS-G is aimed at family houses and small businesses: it stores the daytime solar surplus for the evening and the night. The battery management system talks to the inverter over RS485, CAN, so the inverter must list Deye BOS-G as an approved battery before you order. Protection rating: IP20, so the units belong in a dry, frost-free indoor room. The range includes separate battery modules and control units, so a system can start at the minimum configuration and grow later within the stack limits that Deye specifies.
Tip from practice
High voltage stacks are matched to the inverter by module count. Check the minimum and maximum number of modules your inverter model accepts before you fix the capacity, because that range decides which configurations will work.
How to choose a Deye BOS-G configuration
The table lists every Deye BOS-G product in this category with the key figures we hold for it. Choose in this order: inverter compatibility first, then usable capacity against evening and night consumption, then power and siting.

Frequently asked questions about Deye BOS-G
What usable capacity does Deye BOS-G offer?
The Deye BOS-G products listed here offer 5.12 kWh of usable capacity, and the modular design lets you add capacity later. Compare usable capacity rather than nominal capacity when you size the system.
Is Deye BOS-G a low voltage or a high voltage battery?
Deye BOS-G is a high voltage battery. It needs an inverter with a high voltage battery input and does not work on a 48 V input.
Which inverters work with Deye BOS-G?
Any inverter that lists Deye BOS-G on its approved battery list. The battery communicates over RS485, CAN. Matching the voltage is not enough on its own, because the inverter and the battery management system must use the same protocol and firmware.
Can a Deye BOS-G system be expanded later?
Yes. Additional modules can be added within the maximum stack size that Deye allows. Keep new modules in the same product family and firmware generation, and expand while the existing pack is still relatively new.
Can Deye BOS-G be installed outdoors?
The range is rated IP20, so it should be installed indoors in a dry, frost-free room.
What is Deye BOS-G used for?
Mainly for family houses and small businesses. It stores the daytime solar surplus for the evening and the night and, with a suitable hybrid inverter, can also supply backup circuits during a grid outage.
Where can I buy Deye BOS-G batteries?
ONSA Plus supplies Deye BOS-G to installers and resellers across Europe. This category lists 3 Deye BOS-G products with current prices and availability, and there is no minimum order.
Usable capacity, backup behaviour and inverter compatibility depend on the specific inverter model, the wiring of the installation and the manufacturer's approved combination list.
