Hi @Frans

both 1959159.vff and 1959209.vff are available on Victron Professional

why do you need 143?

After upgrading to 195159 with batteries fully charged I get intermittent trip and restart even with relatively low load added. Indication on inverter "low bat + temperature" LED. The system worked perfectly with the 143 firmware. Also at times change over to shore power with high loads but also not as programmed.
