Its not clear if the the Victron guide https://www.victronenergy.com/live/battery_compatibility:pylontech_phantom#minimum_battery_sizing_recommendations applies both to the US 2000 and US 3000 models . The US3000 model is 50% larger yet it seems from the guide that the minimum number of modules are same for both US2000/3000. The article title says US 2000 / 3000 however the paragraph showing the minimum battery size only mentions the US 2000 model
The guide seems to be written around US2000’s, and their quantities mostly derived from the pylontech current limit of 50% I believe. Therefore 4 x US2000 would be the rough equivalent of 3 x US3000
There was a post elsewhere on this forum where a guy had issues with 3 x 3500 Pylontechs on a 5000 Quattro . The solution said that he must have a minimum of 4 units are per the guide -see https://community.victronenergy.com/questions/32479/quatro-5000-and-three-us300b-pylontechs.html Has the 3500 Pylontech been signed off as approved by Victron then with with 3 or 4 units for a 5000 Multiplus/Quattro.
What is the official answer , will 3 or 4 Pylontech 3500 batteries be satisfactory for a 5000 W/48V
Multiplus?
