August 22, 20205 yr Hello Members, I am new to this forum. I have 8kw deye inverter (same as sunsynk) i would like to find out if anyone was successful in using the lithium mode. I use a GSL Powerwall LIfe po4 battery 200ah. Any Help will highly be appreciated.
August 23, 20205 yr You will need to contact Deye and ask them if your specific brand of battery can be controlled through BMS by the Deye inverter. Normally they would have tested popular Lithum batteries like pylontec, Dyness etc. If they have tested your battery then they would be able to tell you if you should use the CAN or RS485 ports as well as any special cabling requirements. With some types of lithium batteries you might find that the BMS cannot be controlled by the inverter. In this case, you will need to treat the battery as a lead-acid type and set the charging and discharging protocol following the battery manufacturer specifications.
