How to read this datasheet

Knox Xerox 40.5kW G4 Pro OnGrid Solar Inverter is listed with 7 published specifications from Knox, including output current of 63.8 A, efficiency of Max 98.7%, European 98.3%, AC voltage range of 160 V – 300 V (Nominal: 230 V / 400 V) and MPP voltage range of 180 V – 1000 V. Those figures are what decide whether this unit fits your system, so read them against the equipment it will connect to before comparing price.

For an inverter, the figures that matter most are maximum PV input and the number of MPPT trackers, which set how many panel strings you can connect, the MPPT voltage window, which decides how many panels go in a string, peak and weighted (European/CEC) efficiency, typically 96–98.5% and topology — on-grid, off-grid, hybrid or micro. It is the component that decides what a solar system can do: how much power you can draw at once, whether you can export to the grid, whether the system keeps running in a blackout, and how well the panels and battery are managed day to day.

Before you buy an inverter

The checks below apply to any inverter. Run them against the specification table above — most disappointing solar purchases are compatible-on-paper units that fail one of these in practice.

Confirm the inverter is approved by your local utility or distribution network before you buy if you intend to export power — grid connection depends on certified anti-islanding and local grid-code compliance, not on the inverter's specifications alone.
Match the battery communication protocol (CAN bus or RS485) between inverter and battery. Compatible voltages are not enough; without a supported protocol the battery management system and inverter cannot agree on charge limits.
Look at the warranty term and what it covers. Five years is the common baseline, ten is offered by stronger brands, and extensions are often cheaper bought with the unit than later.
Size the inverter against the loads you need to run simultaneously, not against the total wattage of every appliance in the building — a 5 kW inverter comfortably runs a fridge, fans, lights and a couple of ACs, but not all of them plus a water pump starting at the same time.

What people get wrong

Buying on peak-watt price alone. A cheap inverter with a narrow MPPT window forces awkward string layouts and can strand a portion of the array.
Ignoring the ambient temperature rating. Inverters derate in heat, so a unit rated 5 kW at 25 °C may deliver noticeably less on a hot roof-adjacent wall at 45 °C.
Assuming any grid-tie inverter keeps the lights on during an outage. Standard on-grid units shut down for safety unless they have a dedicated backup or islanding output.

Price and availability

Knox Xerox 40.5kW G4 Pro OnGrid Solar Inverter is listed at ₨ 405,000 (PKR). Solar pricing moves with supply, import duties and exchange rates, and distributors set their own margins, so treat this as a comparison reference and confirm the current figure before you order.

SolarBazaar compares equipment rather than selling it. Shortlist here on specification and price, then buy from an authorised distributor or installer in your country: warranty cover on solar hardware is normally honoured through the channel you bought from, so confirm who supports Knox locally before ordering.

Knox Xerox 40.5kW G4 Pro OnGrid Solar Inverter — frequently asked questions

How much does Knox Xerox 40.5kW G4 Pro OnGrid Solar Inverter cost?

Knox Xerox 40.5kW G4 Pro OnGrid Solar Inverter is listed at ₨ 405,000 (PKR). The figure is indicative — solar prices move with supply, duties and exchange rates, and each distributor sets its own margin — so confirm the current price with a supplier before ordering.

What are the specifications of Knox Xerox 40.5kW G4 Pro OnGrid Solar Inverter?

We hold 7 published specifications for this inverter, including output current 63.8 A, efficiency Max 98.7%, European 98.3%, AC voltage range 160 V – 300 V (Nominal: 230 V / 400 V), MPP voltage range 180 V – 1000 V and MPPT 4 independent MPPTs for optimized energy harvest.

Who makes Knox Xerox 40.5kW G4 Pro OnGrid Solar Inverter?

Knox Xerox 40.5kW G4 Pro OnGrid Solar Inverter is a Knox product, listed under inverters with model reference KNOX-89. The Knox brand page lists the rest of its range so you can compare across the catalogue.

Is Knox Xerox 40.5kW G4 Pro OnGrid Solar Inverter right for my system?

That depends on what it has to connect to. For an inverter, check peak and weighted (European/CEC) efficiency, typically 96–98.5%, topology — on-grid, off-grid, hybrid or micro and continuous AC output in kW, which caps the load you can run at once against the rest of your equipment before price enters the decision. Keep the panel array between roughly 1.0 and 1.3 times the inverter's rating. Slight oversizing (a higher DC-to-AC ratio) captures more energy on cloudy mornings and winter days; going far beyond it wastes generation through clipping.

Where can I buy Knox Xerox 40.5kW G4 Pro OnGrid Solar Inverter?

SolarBazaar lists and compares equipment rather than selling it. Use the specifications and price here to shortlist, then buy through an authorised distributor or installer — buying in-channel is what keeps the manufacturer's warranty valid.
