Please update to the latest firmware which is 487.

Just a quick question is the power switch in inverter mode or charger only?

Has the inverter been setup using VE. Configure? Is all your ESS settings correct in the assistant?

Thanks shaneyake,

After posting yesterday and more reading I realized that although the system tells me it has the latest firemware there are in fact later versions. I have downloaded v487 and will update asap.

Switch is in inverter.

System was setup with VE configure, ess & current sensor assistance installed and setup.

Thanks for your help. I expect the firmware upgrade will sort the problem.

Colin
