FEATURED SOLAR CHARGE CONTROLLERS
30 AMP Solar Charge Controller 12/24 Volt PWM
A pulse width modulation controller for compact builds, with a digital display for reading amps or battery voltage at a glance.
- Best For: small do-it-yourself solar projects, RV roof arrays, and battery maintenance
- Output: 30 amps maximum charging current on a 12 or 24 volt battery
- Handles a 400 watt panel array at 12 volts or 800 watts at 24 volts, with a 27.5 volt maximum open circuit voltage input
- Charges lithium, open lead acid, sealed, and AGM batteries, with reverse polarity, overload, short circuit, and high temperature protectionÂ
Solar Charge Controller 30 AMP MPPT 12/24 Volt, Compact with USB
A compact maximum power point tracking controller that harvests more watts from the same solar array than a PWM controller can.
- Best For: vans, RVs, and small off-grid cabins where panel space is limited
- Output: 30 amps to a 12 or 24 volt battery bank
- MPPT tracking delivers up to 99% energy conversion, so more of what the array produces reaches the battery
- Â Built-in USB output charges phones and small electronics through the same unit
60 Amp MPPT Solar Charge Controller, ETL Listed UL 458/CSA 22.2
Our certified MPPT controller for large systems, with an LCD that reports panel voltage and wattage, charging current, charge state, and total kWh produced.
- Best For: Commercial off-grid installs, solar kits, and battery backup banks
- Output: 60 amps of maximum battery current, with a 60 amp DC load port
- Tracks at 97.5 to 99% efficiency on 12, 24, 36, and 48 volt systems, with PV input voltage accepted up to 155 VDC
- Four stage charging with an included battery temperature sensor, plus an RS485 port for computer monitoring
APPLICATIONS
Find the Right Solar Charge Controller for Your Build
Solar
Installers
Size the controller to the array’s maximum power and open circuit voltage, then confirm the current range covers peak output in full sun.
RV Manufacturers and Dealers
Mount a compact controller behind a wall panel and run roof solar into the house bank without adding weight to the coach.
Work Trucks and Fleet Vehicles
Hold an auxiliary battery at charge between jobs so crews are not idling the engine to keep equipment running.
OEMs and Upfitters
Spec a controller into your product at volume pricing and talk through wiring, load terminals, and battery pairing with our engineers before the build.
BUS & VAN MANUFACTURERS AND OPERATORS
Support onboard loads and passenger electronics with steady daytime charging from the roof array.

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.

Frequently Asked Questions
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.
