Just recieved this from the technical department of Bimble solar. “The Dyness should be fine with the Sunsynk. The ECCO 8.8kW can charge at 190A. In 5 hours it can therefore do an absolute maximum of 950Ah. Each Dyness module is 100Ah, so within a 5h window, they should be OK. Normally batteries are not completely discharged, so not requiring a full 900Ah to get them back to 100%.”
Sunsynk inverter adapts Li-ion battery charging to self-adapt to what the battery BMS tells it to do. In other words its supplies only what the battery BMS calls for. The inverter won’t be 100% efficient but, will not cause a bottleneck imo.
The Dyness DL05c charge and discharge currents plus batter temp will play a part in the absolute maximum it will sustain a charge/discharge.
