Using Lithium (LIFE PO) on Multiplus (Inverter only)

I have a Multiplus 12V 3000W 240V inverter with firmware xxxx400 or higher. I run it for domestic off-grid use and never use this device to charge batteries. It only ever inverts DC to AC. I use an epever MPPT to charge batteries. Been running off-grid for 4 years now with no issues except the 120aH lead acid batteries are down to about 10/20aH now. Despite asking in 2023 and in spite of several people kindly offering comments and advice I still don't know whether it's safe to just run the lithium battery (LIFE PO) I have just purchased. The multiplus manual offers virtually no information on this subject (only mentioned in Programmable analog/digital input/output ports..I don't have, or even really wish to have, a VE connect dongle. Assuming there are no upstream issues with the batteries/MPPT/Fuses etc does anyone know whether it's safe to use LIFE PO as a power source for the inverter?


Thanks.

What are the first two digits is it 26 or 23? If so, you can update firmware and it would support lithium profiles.

You need to open the front top cover to see the chip.

You will need an mk3 to usb adaptor or a GX to update firmware.

Ok, so with a mk3 you will be able to update it to a current version.
