How to read this datasheet

SolarMax 20kW 3-Phase On-Grid Inverter is listed with 10 published specifications from SOLARMAX, including display of Wireless (Bluetooth)& APP+LED+LCD, IP rating of IP66, start voltage [V] of 180V and tropology of Transformerless. 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.

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.

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.
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.

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 in Pakistan

SolarMax 20kW 3-Phase On-Grid Inverter is listed at ₨ 280,000 (PKR) for Pakistan. 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 Pakistan: warranty cover on solar hardware is normally honoured through the channel you bought from, so confirm who supports SOLARMAX locally before ordering.

SolarMax 20kW 3-Phase On-Grid Inverter — frequently asked questions

How much does SolarMax 20kW 3-Phase On-Grid Inverter cost?

SolarMax 20kW 3-Phase On-Grid Inverter is listed at ₨ 280,000 (PKR) for Pakistan. 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 SolarMax 20kW 3-Phase On-Grid Inverter?

We hold 10 published specifications for this inverter, including display Wireless (Bluetooth)& APP+LED+LCD, IP rating IP66, start voltage [V] 180V, tropology Transformerless and cooling Natural cooling. The full table is on this page, listed under model SOLM-1.

Who makes SolarMax 20kW 3-Phase On-Grid Inverter?

SolarMax 20kW 3-Phase On-Grid Inverter is a SOLARMAX product, listed under inverters with model reference SOLM-1. The SOLARMAX brand page lists the rest of its range so you can compare across the catalogue.

Is SolarMax 20kW 3-Phase On-Grid 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 SolarMax 20kW 3-Phase On-Grid Inverter in Pakistan?

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 in Pakistan — buying in-channel is what keeps the manufacturer's warranty valid.
