What these specifications mean

Detailed specifications for SunMaxx Solar Charge Controller 20A with 2 USB Port have not been published yet. SunMaxx lists this charge controller in the Charge Controllers, and we add fields as the manufacturer releases them — in the meantime, ask your distributor for the datasheet before ordering.

For a charge controller, the figures that matter most are conversion efficiency, typically 96–99% for a good MPPT unit, whether it offers a load output, temperature compensation and remote monitoring, type: MPPT or PWM and rated charge current in amps, which must exceed the array's short-circuit current with margin. In any system with a battery and a separate array, the controller is what protects the most expensive component and determines how much of the array's output actually reaches storage.

A solar charge controller sits between the panels and the battery, regulating voltage and current so the battery charges correctly and is never overcharged or drained back into the array at night.

What to check before ordering

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

Prefer a unit with temperature compensation or a battery temperature sensor if the bank lives somewhere that gets hot or cold.
Choose MPPT over PWM for anything beyond a very small array. An MPPT controller harvests roughly 20–30% more energy because it converts excess panel voltage into charge current instead of throwing it away.
Size the current rating from array watts divided by battery voltage, then add at least 25% margin for cold, bright conditions where panels exceed their rated output.
Check the maximum PV input voltage against the array's Voc at your coldest expected temperature, not at 25 °C — Voc rises as temperature falls, and exceeding the limit destroys the controller instantly.

Common mistakes

Sizing on rated array watts alone and ignoring the voltage ceiling, which is the most common way controllers are killed.
Using a PWM controller with a high-voltage grid-tie panel — the voltage mismatch wastes a large share of the panel's output.
Running the load output beyond its rating instead of wiring heavy loads directly to the battery through a fuse.

Price and availability in Pakistan

SunMaxx Solar Charge Controller 20A with 2 USB Port is listed at ₨ 3,000 (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 SunMaxx locally before ordering.

SunMaxx Solar Charge Controller 20A with 2 USB Port — frequently asked questions

How much does SunMaxx Solar Charge Controller 20A with 2 USB Port cost?

SunMaxx Solar Charge Controller 20A with 2 USB Port is listed at ₨ 3,000 (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.

Who makes SunMaxx Solar Charge Controller 20A with 2 USB Port?

SunMaxx Solar Charge Controller 20A with 2 USB Port is a SunMaxx product, listed under charge controllers with model reference SUNX-02. The SunMaxx brand page lists the rest of its range so you can compare across the catalogue.

Is SunMaxx Solar Charge Controller 20A with 2 USB Port right for my system?

That depends on what it has to connect to. For a charge controller, check conversion efficiency, typically 96–99% for a good MPPT unit, whether it offers a load output, temperature compensation and remote monitoring and type: MPPT or PWM against the rest of your equipment before price enters the decision. Size the current rating from array watts divided by battery voltage, then add at least 25% margin for cold, bright conditions where panels exceed their rated output.

Where can I buy SunMaxx Solar Charge Controller 20A with 2 USB Port 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.
