Common Questions
Click a question below to reveal the answer.
Does the Fox ESS F3600 G3 include a DC isolation switch?
No. The DC switch is an optional feature on the F Series G3 range. This inverter does not include an in-built DC isolator as standard.
What is the advantage of dual MPPT on the Fox ESS F3600 G3?
The two independent MPPT trackers allow separate string orientations, roof faces, or shading zones to operate independently, improving total system yield compared to a single-MPPT inverter.
Can the Fox ESS F3600 G3 be used with battery storage?
The F3600 G3 is battery ready. It can be upgraded to include storage when paired with a Fox ESS charge controller.
Does the Fox ESS F3600 G3 include WiFi monitoring?
Yes. The F3600 G3 includes an internal WiFi module as standard for monitoring via FoxCloud V2.0. Optional external 4G and LAN modules are also available.
What are the dimensions and weight of the Fox ESS F3600 G3?
