Overview

Description

The ProteusX is ACOPOWER's first waterproof PWM charge controller. It is a negative ground controller. This ensures compatibility with any negative ground system, which is the standard and most conventional way of grounding.

Featuring a bright blue back-lit LCD display system, including error codes. Designed and engineered to world-class quality standards. Not only is it waterproof, but it is also equipped with advanced PWM technology suitable for 12V and 24V off-grid applications, and compatible with 8 different battery types, including Lithium.

With multiple controller protections, you're assured solar system longevity and protection with the ProteusX 20A charge controller.

How to read this datasheet

Detailed specifications for ProteusX 20A PWM Solar Charge Controller have not been published yet. ACOPOWER 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 whether it offers a load output, temperature compensation and remote monitoring, type: MPPT or PWM, rated charge current in amps, which must exceed the array's short-circuit current with margin and maximum PV open-circuit voltage, the hard limit that must survive cold-morning Voc rise. 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.

Before you buy a charge controller

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.

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.
Confirm the controller supports your battery chemistry with the right charge profile. Lithium, AGM, gel and flooded batteries need different absorption and float voltages.
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.

What people get wrong

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 Australia

ProteusX 20A PWM Solar Charge Controller is listed at A$ 96 (AUD) for Australia. 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 Australia: warranty cover on solar hardware is normally honoured through the channel you bought from, so confirm who supports ACOPOWER locally before ordering.

ProteusX 20A PWM Solar Charge Controller — frequently asked questions

How much does ProteusX 20A PWM Solar Charge Controller cost?

ProteusX 20A PWM Solar Charge Controller is listed at A$ 96 (AUD) for Australia. 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 ProteusX 20A PWM Solar Charge Controller?

ProteusX 20A PWM Solar Charge Controller is a ACOPOWER product, listed under charge controllers with model reference HY-PWM-PX20A. The ACOPOWER brand page lists the rest of its range so you can compare across the catalogue.

Is ProteusX 20A PWM Solar Charge Controller right for my system?

That depends on what it has to connect to. For a charge controller, check supported battery voltages (12/24/36/48 V) and chemistries, conversion efficiency, typically 96–99% for a good MPPT unit and whether it offers a load output, temperature compensation and remote monitoring 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 ProteusX 20A PWM Solar Charge Controller in Australia?

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