NoordSolar Posted May 22, 2022 Posted May 22, 2022 SolarMD recommend a mx charge voltage of 54.6V - 3.4 V/cell ( reported on the Victron website - they don't seem to provide this info on their own site ) This voltage is much lower than their peers and am wondering what the actual BMS high voltage trip voltage is ? Anyone know ? I would like to parallel this with another bank which I sometimes take to 56V for the occasional balance Quote

giorgos Posted June 16, 2022 Posted June 16, 2022 My victron settings for the 7,4 kwh solarMD battery are Absorption voltage 54.6 V Float voltage 53.4 V Equalization voltage 54.6 V above values as recommended by SolarMD by the way the solarMD batteries do not require balancing. Quote
Wetkit Posted June 23, 2022 Posted June 23, 2022 Is there any way to get the SolarMD unit to "talk" or communicate to a Goodwe inverter? Quote
TCB Posted February 24, 2023 Posted February 24, 2023 I am unable to get my SolarMD battery to communicate with SolarAssistant - any assistance is welcome please. Quote

If not, have you been in contact with them to see how you can enable the "Emulated BMS" ? Let SolarAssistant perform it's own state of charge (SoC) calculation by counting power flowing in and out of the battery. This is a good fallback option for anyone who can't get a real BMS reading. It's less accurate than a Victron BMS but much more accurate than the standard voltage based readings of an inverter https://solar-assistant.io/help/battery/configuration Quote
TCB Posted February 25, 2023 Posted February 25, 2023 (edited) It is on the list, I emailed them this morning - hopefully someone will assist. I am using Emulated BMS now, but it is less accurate. I was just looking for someone with the same setup to assist. Thanks! Edited February 25, 2023 by TCB Quote
TCB Posted February 28, 2023 Posted February 28, 2023 Evening all, problem is fixed. SolarAssist gave me the wrong cable. Everything is working now - I can confirm that SolarMD battery and Mecer Axpert 5.6K MKS IV 5600VA / 5600W 48V MPPT Inverters (SOL-I-AX-5M4) will work together with SolarAssist. Quote
