January 2, 20215 yr Hello I have a friend that wants to go full Victron. (He has been having endless issues with other brands) He has now replaced his MPPT's with 2x Victron BlueSolar Charge Controller 150/85. This is charging a Lithium 7.4 SolarMD battery. He now wants to replace his 5kw inverter but he is not sure which Victron inverter will meet his requirement of being a hybrid but being able to run Solar first, then utility, and only then Battery (SUB basically instead of the SBU). Any recommendations and what extra Victron components is needed in order for every thing to communicate correctly? Thanks
January 2, 20215 yr Hi, IMO best choice your friend has ever made and he would look back Warning becomes costly maar Goedkoop is Duurkoop!!! Depending on his setup/needs GX device Cerbo or Venus Multiplus II 5 kva or Quattro MK3 cable ET112 with RS485 to USB Cables to connect MPPT's to GX device/Multi to GX And cable to connect battery to GX (https://www.victronenergy.com/live/battery_compatibility:solar_md) FYI get someone that is victron certfied to install not simple as voltronic and other setups Not to worry Victron is very versatile that way, works intelligently Edited January 2, 20215 yr by Quwatush Shams (Suly)
January 2, 20215 yr Sorry made a typo meant he WONT look back Use a busbar for battery/mppts and check out https://www.victronenergy.com/upload/documents/Wiring-Unlimited-EN.pdf for correct cable sizing Edited January 2, 20215 yr by Quwatush Shams (Suly)

January 4, 20215 yr As far as I understand it the ESS software (runs on the GX device) will do this if you select " Keep Batteries Charged" option. Other options are optimize for battery life , optimized and external control -- the optimized settings will use the battery and PV to try and reduce grid usage as much as possible.
