How to read this datasheet
1ON Photon Series 4.2KW 24V PV5500 Off-Grid Solar Inverter is listed with 13 published specifications from 1ON, including transfer time of 10ms (UPS Mode) / 20ms (Appliance Mode), rated power of 4.2KW, battery compatibility of Lithium & Lead-Acid and battery voltage of 24V DC. 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.
Choosing an inverter: the checks that matter
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.
- Check the surge rating if you run motors — deep-well pumps, compressors and older air conditioners can draw two to three times their running current for a few seconds at start-up.
- Choose a hybrid inverter if a battery is in your plan now or later; retrofitting storage onto a pure grid-tie inverter usually means buying a second unit or an AC-coupled battery system.
- 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.
Common mistakes
- 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
1ON Photon Series 4.2KW 24V PV5500 Off-Grid Solar Inverter is listed at ₨ 110,000 (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 1ON locally before ordering.
1ON Photon Series 4.2KW 24V PV5500 Off-Grid Solar Inverter — frequently asked questions
How much does 1ON Photon Series 4.2KW 24V PV5500 Off-Grid Solar Inverter cost?
1ON Photon Series 4.2KW 24V PV5500 Off-Grid Solar Inverter is listed at ₨ 110,000 (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 1ON Photon Series 4.2KW 24V PV5500 Off-Grid Solar Inverter?
We hold 13 published specifications for this inverter, including transfer time 10ms (UPS Mode) / 20ms (Appliance Mode), rated power 4.2KW, battery compatibility Lithium & Lead-Acid, battery voltage 24V DC and communication RS232 / RS485. The full table is on this page, listed under model 1ON-03.
Who makes 1ON Photon Series 4.2KW 24V PV5500 Off-Grid Solar Inverter?
1ON Photon Series 4.2KW 24V PV5500 Off-Grid Solar Inverter is a 1ON product, listed under inverters with model reference 1ON-03. The 1ON brand page lists the rest of its range so you can compare across the catalogue.
Is 1ON Photon Series 4.2KW 24V PV5500 Off-Grid Solar Inverter right for my system?
That depends on what it has to connect to. For an inverter, check continuous AC output in kW, which caps the load you can run at once, surge or peak rating, which covers the brief inrush of motors and compressors and maximum PV input and the number of MPPT trackers, which set how many panel strings you can connect against the rest of your equipment before price enters the decision. Choose a hybrid inverter if a battery is in your plan now or later; retrofitting storage onto a pure grid-tie inverter usually means buying a second unit or an AC-coupled battery system.
Where can I buy 1ON Photon Series 4.2KW 24V PV5500 Off-Grid 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.
