MPPT 250/60 and 18s DIY LiFePo

Hi, are the MPPTs also suitable for 18s LiFePo batteries? The MultiPlus II could be configured for the higher voltage. But can the MPPT also handle the higher voltage?

Check the manual for the settings range. Or download Victron connect and experiment in the demo library

thanks. I tried the Victron connect app and did some experiments with the Smart Solar charger. Theoretically you can select a 48V battery and adapt the voltages to a 18s battery pack. The value for absorption 62.1V (18x3.45V) is accepted. The max. value can be 69.56V. So it seems, that it should work. Or does the preselection of 48V has any impact? Does anybody tried such a setup? The guy from MeinTechBlog.de has a 18s battery setup. But he has only an AC inverter and no Solarchargers.

Selecting 48V sets defaults which you can override as you did in the app.
