Common Questions
Click a question below to reveal the answer.
What is the advantage of dual MPPT on the Fox ESS F3000 G3?
The two independent MPPT trackers allow separate string orientations, roof faces, or shading zones to operate independently. This improves total system yield compared to a single-MPPT inverter on multi-aspect roofs.
Can the Fox ESS F3000 G3 be used with battery storage?
The F3000 G3 is battery ready. It can be upgraded to include storage when paired with a Fox ESS charge controller.
What is the maximum DC input and DC/AC ratio on the Fox ESS F3000 G3?
The F3000 G3 accepts up to 6,000 W total DC input (maximum 4,000 W per MPPT) against a 3,000 W rated AC output, giving a 2:1 DC/AC ratio.
What are the dimensions and weight of the Fox ESS F3000 G3?
The F3000 G3 measures 358 x 335 x 155 mm (W x H x D) and weighs 9.5 kg or less. It is a single-person lift and install.
Does the Fox ESS F3000 G3 include WiFi monitoring?
Yes. The F3000 G3 includes an internal WiFi module for monitoring via the FoxCloud V2.0 platform. External 4G and LAN monitoring modules are also available as options.
