  1. Sunsynk 3 x 16kw max 3 phase F26 bus unbalance fault

    Divan Du Toit SST posted a topic in Inverters
    Hi All, i have a client with the following setup. They keep experiencing issues when its loadshedding , as soon as the power goes out, they get a F26 Bus unbalanced fault on the master modbus 01 inverter. Then they loose power over all 3 phases because of the on inverter that died. We have checked the PV for earth leakage, we checked the lightning arrestors. Changed them aswell, with no luck. They only experience this when the PV side of things is low and there is no grid. Mabey once in 2 months. We are stuck on why this would happen, any help we will appreciate. Phase A - Inverter 1 - Modbus 01 Phase B - Inverter 2 - Modbus 02 Phase C - Inverter 3 - Modbus 03 They all go to a common DC busbar. Inverter 1 - with the fault codes load on the inverter. Inverter 2 Inverter 3
