3.6kw inverter largest solar array that can be used.
Keith on his videos says the 3.6kw inverter can have a 7000 watt array added to the inverter. is this correct. I have a system of 3.2kw array using 8 x 400 watt sharp solar panels . 3.6 kw inverter and 5.2.kw battery both sunsynk. Could the inverter handle another 4x 400 0r 450 watt sharp solar panels to produce more electricity in the winter when we don't fill up the battery in the November/Dec /Jan and February months. please advice.

Just as a further example of how to build out a system to full utilisation, I have 2 * 3.6kW inverters in parallel, each inverter has 2 strings of 3.6kW (8 * 450CS = 3.6kW - VOC of 49v = 392v Max) in total I have mounted 14.4kW of Solar - split between East & West aspect roof. I am utilising the Grid input / output @ 16A on each and utilising the Load / UPS output @ 16A on each, the following settings only need to be made on the Master, the slave replicates,
Max Charge rates are set at 72A (50V * 72A = 3600kW) on each, Discharge rates are set at 40A (50v * 40A = 2kW) on each. I have 4 * 5.12 Sunsynk CATL batteries in parallel charged / discharged by both invertors via 120A DC Fused Isolators to each invertor joined on a busbar. The principle I am working to is being able to utilise 7.2kW AC when available and be able to charge batteries with the surplus all at the same time - predominantly in the Summer when both roof aspects will receive sun for 4 hrs around Midday, but the East roof will start generating at Sunrise around 4.45AM and the West will see the sun through to 10PM. the charge / discharge times are set between 15% SOC and 90% SOC and will be adjusted through the seasons to suit. So far I am pleased with the generation considering we are only in January and cloudy days managing 7kW...here's to the brighter months!
