SolaX LV at a glance
SolaX LV 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 LV as an approved battery before you order.
Protection ratings in this range: IP65, IP66. Units rated IP54 or higher can be mounted outdoors within the temperature limits in the datasheet.
Tip from practice
Low voltage packs run at about 48 V and therefore carry high current. Size the DC cable and the fuse for the full discharge current, not for the average load, and keep the cable run between battery and inverter short.
How to choose a SolaX LV configuration
The table lists every SolaX LV 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.

Is SolaX LV a low voltage or a high voltage battery?
SolaX LV is a low voltage battery. It connects to inverters with a 48 V battery input.
Which inverters work with SolaX LV?
Any inverter that lists SolaX LV 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 SolaX LV 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 IP65, IP66.
What is SolaX LV 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 LV batteries?
ONSA Plus supplies SolaX LV to installers and resellers across Europe. This category lists 2 SolaX LV 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.
