Is there a rule of thumb as to how many watts of panels to inverter output?. Let's say for example we have an MPP LVX6048 inverter rated at 6000 watts, what amount of PV would be required for the inverter to operate correctly and produce full power?. This inverter has the option to operate using PV-only output to load as an option. Let's say I only a have 3kw array connected to it, running in PV output mode would it put out the rated 6kw output?.
