AIMS Power manufactures MPPT and PWM solar charge controllers in 10 to 100 amp sizes for 12, 24, 36, and 48 volt systems. A solar charge controller sits between the solar panel array and the battery bank, regulating current and battery voltage so the bank reaches a full charge state without overcharging.
A pulse width modulation controller for compact builds, with a digital display for reading amps or battery voltage at a glance.
A compact maximum power point tracking controller that harvests more watts from the same solar array than a PWM controller can.
Our certified MPPT controller for large systems, with an LCD that reports panel voltage and wattage, charging current, charge state, and total kWh produced.
Size the controller to the array’s maximum power and open circuit voltage, then confirm the current range covers peak output in full sun.
Mount a compact controller behind a wall panel and run roof solar into the house bank without adding weight to the coach.
Hold an auxiliary battery at charge between jobs so crews are not idling the engine to keep equipment running.
Spec a controller into your product at volume pricing and talk through wiring, load terminals, and battery pairing with our engineers before the build.
Support onboard loads and passenger electronics with steady daytime charging from the roof array.
Asked a question after business hours regarding compatabilitgy of controller and had an answer the next morning before noon. Received the perfect answer from Angel Cruz.
I had a super technical question with a lot of components in a motorhome. Aims Inverter/Charger, Aims Solar Charge controller. I wanted to know how to handle mismatched chassis and house battery types into the whole system and how it impacted the alternator charging circuit with LifePO4 house batteries. A tech got back to me within a few hours and told me exactly what I needed to purchase. Great job tech assistance!
I am unfamiliar with solar system technology. I bought a 100Amp charge controller from Aims Power. I called for technical assistance. Angel has been very helpful and professional in helping me with my problems. I highly recommend him and his company. Especially if you are a novice thanks.
It regulates the voltage and current flowing from the solar panel to the battery, holding the bank at the right charge state and stopping overcharge. A direct connection between a panel and a battery can push higher voltage into the bank than the battery is designed to handle.
A PWM controller costs less and works well when panel voltage sits close to battery voltage, which fits small systems and float charging. An MPPT charge controller converts surplus panel voltage into extra charging current, so it returns more power to the battery and pays back the higher purchase price on larger systems.
Divide the array’s total watts by the battery voltage for rough charging amps, then choose a controller with headroom above that figure for full sun. Check the array’s open circuit voltage against the controller’s maximum input voltage before ordering. If you have not settled on an array yet, our solar calculator totals the watts your loads need and recommends a kit, and you can size the controller from there.
The load terminals let you run DC equipment like lighting or a pump straight off the controller, with low voltage disconnect protecting the bank. It is a convenience for small loads, not a substitute for an inverter, which is what you need for anything running on AC power.
Yes. An inverter turns battery power into AC, and a DC-DC converter steps voltage up or down for DC loads. Neither regulates panel output, so any array charging a bank needs its own controller, plus PV wire and a disconnect switch sized for the job.
