What these specifications mean
Power Square VM-IV 4kW Twin Hybrid Solar Inverter is listed with 11 published specifications from Power Square, including battery voltage of 24 VDC, efficiency of 90% - 93%, transfer time of 10 ms (for personal computers) 20 ms (for home appliances) and rated power of 4000VA/4000W. 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 surge or peak rating, which covers the brief inrush of motors and compressors, 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 and peak and weighted (European/CEC) efficiency, typically 96–98.5%. 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.
An inverter converts the direct current (DC) produced by solar panels and stored in batteries into the alternating current (AC) that household appliances, pumps and the utility grid actually use.
What to check before ordering
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.
- 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.
- 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.
Common mistakes
- Overlooking the IP rating. An outdoor installation needs at least IP65; indoor-rated units mounted outside fail early.
- 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.
Price and availability
Power Square VM-IV 4kW Twin Hybrid Solar Inverter is listed at ₨ 124,000 (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 Power Square locally before ordering.
Power Square VM-IV 4kW Twin Hybrid Solar Inverter — frequently asked questions
How much does Power Square VM-IV 4kW Twin Hybrid Solar Inverter cost?
Power Square VM-IV 4kW Twin Hybrid Solar Inverter is listed at ₨ 124,000 (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 Power Square VM-IV 4kW Twin Hybrid Solar Inverter?
We hold 11 published specifications for this inverter, including battery voltage 24 VDC, efficiency 90% - 93%, transfer time 10 ms (for personal computers) 20 ms (for home appliances), rated power 4000VA/4000W and surge power 8000VA. The full table is on this page, listed under model POSE-05.
Who makes Power Square VM-IV 4kW Twin Hybrid Solar Inverter?
Power Square VM-IV 4kW Twin Hybrid Solar Inverter is a Power Square product, listed under inverters with model reference POSE-05. The Power Square brand page lists the rest of its range so you can compare across the catalogue.
Is Power Square VM-IV 4kW Twin Hybrid Solar Inverter right for my system?
That depends on what it has to connect to. For an inverter, check topology — on-grid, off-grid, hybrid or micro, continuous AC output in kW, which caps the load you can run at once and surge or peak rating, which covers the brief inrush of motors and compressors against the rest of your equipment before price enters the decision. 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.
Where can I buy Power Square VM-IV 4kW Twin Hybrid 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.
