The Fox ESS KH10 is a 10kW single-phase hybrid inverter for a 220/230/240V AC, 50/60Hz grid connection, with a 20,000W maximum PV array rating, 4 MPP trackers and an IP65 wall-mounted enclosure. It suits larger single-phase solar and storage installations where the design calls for the retained 10kW KH model, with high-voltage battery operation and EPS output available where the system is designed for it.

• 10kW nominal AC power with 43.5A nominal current and 45.7A maximum AC current
• 220/230/240V AC single-phase grid connection at 50/60Hz
• 4 MPP trackers with one string per tracker and 600V maximum DC voltage
• Meter optional, Wi-Fi, 4G optional, DRM, USB, CT and RS485 communications
• PV reverse polarity, battery reverse, anti-islanding, leakage-current and Type II AC and DC surge protection
• 450mm wide x 527mm high x 208mm deep, 29kg for the KH model
• IEC 62109-1, IEC 62109-2, IEC 62477-1 and G99 listed in the datasheet

Who should use the 10kW KH model?

KH10 is the highest-output retained KH product in this batch. It suits single-phase projects that need 10kW nominal AC output and four MPPT inputs, subject to grid connection, export and installation design.

It should be created as a new retained page and not merged with the old KH10.5 product. KH10.5 remains a different model identity and should only redirect to KH10 if you decide KH10 is the commercial replacement.

What PV capacity can KH10 handle?

The KH10 datasheet lists 20,000W maximum array power and 15,000W maximum DC input power. It uses four MPP trackers, each with one string, with 600V maximum DC voltage.

The 80V to 500V MPPT range and 75V start-up voltage should be checked against the module selection. Array oversizing, string voltage and input-current limits need to be documented before the product is quoted.

How should old KH10.5 traffic be handled?

KH10 should be the retained 10kW page, while KH10.5 should not be silently rewritten into this product. If the old KH10.5 page is removed, use a redirect to KH10 only where you are comfortable treating KH10 as the replacement.

If not, leave KH10.5 as discontinued with noindex or redirect it to the Fox ESS category. This avoids mismatching a 10.5kW historical model with the current 10kW retained product.
