Multplus II Settings Pylontech 4*US5000

Hi

as there's no template settings for the PT US5000: what are the advised settings for the inverter/charger settings for this type of battery? I will propably never use the charger but still the charging window and the floating voltage seems pretty important anyway. I plan to use the advised settings from VE which is load max. 52.0V; max charge 50A and DoD of 88% = SoC 12%.

What (voltage) settings should be used? The DC settings in the ESS seems pretty harsh when the LFP settings for external BMS is used.

Cheers

Michael

Follow this guide and all the setup/settings,then it should work just fine:

The pylontech bms will force dvcc on and makes sure the batteries charge/discharge the right way

4. GX Device Settings

When the Pylontech battery is connected to the BMS-Can port of a GX device (running v2.80 and later) the following DVCC settings will be set and enforced automatically.

Hello Duivert NL & gonzalor

thanks for the link: those answers all the settings. While I already read it, it seems I jumped completely over the ESS Settings. Today I did set all the settings and used the ESS Assistent and reset floating+Absorption voltage after the assistent is finished. While the battery is at 50% SOC the L1 Multiplus (3phase) shows Low Voltage alarm. The MP II's have firmware 5.5.2.

Any Idea where to search?
