KNOX XEROX G4 Pro 20k/30kpV 32A/32A- Maximum Output 22kW

✅ What is XEROX G4 Pro 20.2kW — main specs & features

• The G4 Pro 20.2 kW is a three-phase on-grid solar inverter with a rated AC output of ~20 kW (20,000 W). 

• On the DC / PV side it supports up to ~30,000 Wp (30 kWp) solar array — meaning you can attach quite a large number/area of solar panels. 

• Input / MPPT / panel-string flexibility:

  • Dual MPPT trackers with 2 strings per MPPT. 

  • Wide MPPT / DC-input voltage range: ~150 V to 1000 V (with max DC input voltage up to ~1100 V depending on PV modules/wiring) — giving good flexibility in how panels are wired (series/parallel, high-voltage strings).

  • Max DC input current per MPPT: 32 A / 32 A. AC output side and grid-connection details:

• • Rated AC output 20 kW, with up to ~22,000 VA apparent power (so ~22 kVA). 

  • Max AC output current ~31.9 A at nominal voltage (per phase arrangement depending on wiring). 

  • Compatible with standard three-phase grid supply (depending on local wiring: 230 V phase to neutral / 3-phase etc.). 

• Build, durability & installation-features:

  • Housing rated IP66 (dust- and water-resistant) → suitable for outdoor / rooftop installation. 

  • Operating temperature range roughly –25 °C to +60 °C — able to handle wide ambient conditions (hot climate like Faisalabad). 

  • Compact, wall-mountable design for easier installation. 

  • It supports “PV oversizing” (i.e. you can connect PV modules whose total Wp is somewhat higher than inverter’s rated wattage) — a common advantage to maximize yield under varying sun / partial shading conditions. 

• Additional features typical for “Pro / G4” series inverters: Advanced MPPT tracking (two independent trackers), wide input flexibility, likely protections (over-voltage, surge, anti-islanding, etc.), and integration with grid / net-metering systems (though for export/usage you’d need correct wiring and policies). The datasheet lists them among G4 Pro series. apacity, flexible on-grid inverter — meant for relatively large solar installations (big houses, small commercial, or heavy load households) and fairly large PV arrays (up to ~30 kWp), with flexibility and robustness for rooftop/outdoor use.

🎯 When / Why G4 Pro 20.2kW Makes Sense (in Pakistan / Faisalabad context)

This inverter is a good match if:

• You plan to install a large solar system — say 20–30 kWp of panels, to generate substantial solar power.

• Your home or building has high electrical demand — heavy appliances, multiple AC units, motors (water pumps), heavier loads (small business, workshop, etc.) — and you need a three-phase, high-capacity inverter.

• You have enough roof space and good orientation to deploy many solar panels (to approach the 30 kWp limit), or plan to oversize panels to maximize yield under variable sun.

• You want durability and suitability for rooftop/outdoor installation — IP66 rating, wide temperature tolerance — which is important given Pakistan’s climate (heat, dust, occasional rain).

• You aim for a more future-proof system: ability to handle expansion, higher loads, or add more panels later without needing a bigger inverter.

In other words — for a “big house + heavy load + large panel array” scenario, G4 Pro 20.2 kW is a strong candidate.

⚠️ What to Check / Potential Limitations / What to Ensure Before Choosing It

• As with any high-power on-grid inverter: you’ll need proper grid connection / wiring (three-phase if required), and possibly net-metering/export permissions if you plan to feed surplus back to grid.

• To get full benefit, you need sufficient roof space + proper panel layout. If panels are under-sized or poorly oriented, you may never reach near 30 kWp, wasting inverter capacity.

• Installation must be done carefully — correct panel string wiring, grounding, surge protection, etc — especially with high DC voltage & currents.

• If your load is moderate or you don’t plan to use full capacity — you may get away with a smaller inverter; an oversized inverter by itself doesn’t give benefit unless matched with matching PV array and load.

• As with any on-grid inverter: during grid outages (load-shedding), unless you have batteries or hybrid setup, you won’t get power — just solar generation won’t supply load if grid is down (standard limitation).

✅ My View — When I’d Recommend G4 Pro 20.2 for a Pakistani/Residential-Commercial Setup

If I were designing a large solar system for a big house or small workshop/business in Faisalabad — with heavy load (ACs, pumps, appliances), and enough roof space — I’d consider G4 Pro 20.2 a very solid, future-proof choice.

It gives capacity, flexibility, and leeway to expand. But — only if you truly need (or plan to use) large output / lots of panels.
