SolaX HS50E at a glance
SolaX HS50E 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 SolaX HS50E as an approved battery before you order.
Protection ratings in this range: IP66. Units rated IP54 or higher can be mounted outdoors within the temperature limits in the datasheet. 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 SolaX 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 SolaX HS50E configuration
The table lists every SolaX HS50E 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 SolaX HS50E
What usable capacity does SolaX HS50E offer?
The SolaX HS50E products listed here offer 5.1 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 SolaX HS50E a low voltage or a high voltage battery?
SolaX HS50E 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 SolaX HS50E?
Any inverter that lists SolaX HS50E 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 SolaX HS50E system be expanded later?
Yes. Additional modules can be added within the maximum stack size that SolaX allows. Keep new modules in the same product family and firmware generation, and expand while the existing pack is still relatively new.
Can SolaX HS50E be installed outdoors?
Units rated IP54 or higher can be installed outdoors within the temperature range in the datasheet. The ratings in this range are IP66.
What is SolaX HS50E 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 SolaX HS50E batteries?
ONSA Plus supplies SolaX HS50E to installers and resellers across Europe. This category lists 4 SolaX HS50E 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.
