KNOX XEROX G4 Pro 60k/90kpV

✅ What we know about “Knox / XEROX G4 Pro 60k/90kpV”

• There is a listing for “KNOX G4 Pro 60k/90kpV 50 KW On‑Grid Solar Inverter With 90000W PV” on a Pakistani retailer site. 

• This listing suggests that the inverter is marketed to support “90,000 Wp PV” (i.e. 90 kWp) array input, while being sold as “50 kW On‑Grid” inverter. 

• The same brand’s smaller G4 Pro / G4 inverter models (10 kW, 20–25 kW, 40.5 kW, 50 kW) do have more detailed specs publicly available: wide MPPT voltage ranges, support for oversizing PV array (e.g. 150%), IP66 (or similar) enclosures, multiple MPPTs/strings, active‑cooling, and grid‑tie protections.  There is (at least in one documented case) official grid‑tie / net‑metering registration under a slightly smaller G4 Pro model (50k / 75kpV) by the local utility/regulatory authority in Pakistan. 

In short: the brand offers large‑capacity inverters under the “G4 Pro” line; there is a product listing labeled “60k/90kpV,” but its stated “AC output” in that listing is 50 kW — which suggests that “60k” in name may not correspond to 60 kW output, but is more an identifier or marketing label.

⚠️ What is Uncertain / Dubious about 60k/90kpV Specification — Buyer Beware

• I could not locate a verified datasheet (with independent certification, e.g. IEC, TÜV, etc.) showing 60 kW rated output plus 90 kWp PV input capacity under official spec. The public spec-sheet for “50 kW” G4 Pro is available — but not for a “60 kW” version.

• The listing with “60k/90kpV” simultaneously calls itself “50 KW On‑Grid Solar Inverter”.  This is contradictory — suggesting that “60k/90kpV” may only refer to PV‑array rating or brand‑naming, not the actual AC output capacity.

• In large inverter / PV manufacturers’ practice, a big jump (e.g. 50 kW → 60 kW rated AC) without proper spec documentation, certifications or third‑party test data is unusual. Lack of external validation raises reliability / performance risk.

• For very large PV array (90 kWp) + inverter, you need substantial roof/panel area, proper configuration, and grid‑side infrastructure (wiring, breakers, meter, net‑metering). If any of these are weak or missing — you may never get promised output or may even risk safety/compliance issues.

✔️ What to Do If You Consider Buying This Model — What to Check & Ask the Seller

If you decide to look at “G4 Pro 60k/90kpV,” do not buy blindly. Instead — verify carefully:

• Ask the seller for a full official datasheet: rated AC output (kW), rated AC current & voltage, MPPT specs, max DC input current/voltage, efficiency, Ukrainian or IEC‑certification.

• Confirm in writing whether “60k/90kpV” refers to AC output or PV‑array input. If output is 50 kW, treat the inverter as a 50 kW class — plan load/array accordingly.

• Ensure your planned solar panel array size, layout, roof strength & orientation are realistic for the claimed PV‑array capacity (90 kWp).

• Check that your grid connection / meter / wiring at your locality supports the inverter output. Also, check if you are eligible for (and correctly apply for) net‑metering / grid‑tie permission.

• Prefer suppliers/installers with good track‑record, after‑sales support, and install proper protective devices (earthing, surge arrestor, DC disconnect, over‑current protection, etc.).

🎯 My View — Is “Knox / XEROX G4 Pro 60k/90kpV” a Trustworthy Option?

I remain skeptical that “60k/90kpV” as listed is a verified, certified 60 kW inverter — the publicly available data suggests it’s marketed as a 50 kW class.

If I were you and needed a high‑capacity inverter, I would treat it as a 50 kW inverter with potential for large PV input (up to ~90 kWp) — but only if I get clear specifications, proper installation, and grid compliance.

If I were investing in a new system requiring 50 + kW output (e.g. commercial, multi‑unit building), I’d also consider reliable inverters from established international brands (with documented certifications) — to reduce risk.
