The AIMS Power 30 Amp MPPT Solar Charge Controller (SCC30MPPT) tracks the maximum power point of your solar array and charges 12V or 24V battery banks at up to 30A. It detects system voltage automatically, accepts up to 100V PV open circuit voltage and is rated for 390W of solar on 12V or 780W on 24V.
It's made for RV and camper systems, off-grid cabins, remote equipment, backup power and marine use. The metal IP30 enclosure is fanless and conformal coated, though not waterproof. An LCD, a 30A DC load port and two USB ports are built in.
AIMS rates MPPT tracking efficiency above 99.5% and peak conversion efficiency up to 98%. Dual-peak and multi-peak tracking helps when part of the array is shaded.
The MPPT range is 23V to 100V DC on a 12V battery and 46V to 100V DC on 24V, so you can wire panels in series. Automatic current and power limiting holds charging to the rated output if the array can produce more.
Choose sealed/AGM (the default), gel, flooded, LiFePO4, Li(NiCoMn)O2 or user defined. Charging runs in bulk, boost (2 hours by default) and float stages. In lithium mode, charging stops at the boost voltage once current falls below a cut-off you can set from 0.2A to 10A (1A default).
The display shows battery voltage, current and capacity, PV voltage and current, charging power, load current, controller temperature, charging status, battery type and faults. A working record counts low voltage events, working days, over current events and full charges.
The load port runs 24 hours by default, or switches on after sunset for a set number of hours for lighting. Float, boost, low voltage disconnect and reconnect points are adjustable from the front buttons.
Protections include PV overvoltage, PV reverse polarity, PV overcurrent limiting, battery overvoltage, over discharge, load overload, load short circuit, night reverse current and transient voltage surge (TVS). Output derates at 75°C and shuts down at 85°C.
RVs and campers. Charge a 12V or 24V house bank from roof panels wired in series.
Marine. Conformal coating suits boats, as long as the controller is mounted in a dry, protected spot.
Cabins and remote equipment. Run an off-grid or backup system with DC lights on the timer-controlled load port.
A PWM controller needs panel voltage matched to the battery. This MPPT controller accepts up to 100V and converts it into charging current, so you can use series strings and higher voltage panels.
The 30A rating carries 390W of solar on a 12V bank and 780W on a 24V bank, so a 24V bank doubles the solar this controller can use.
Cold raises panel voltage. Keep the array's temperature-corrected open circuit voltage under 100V at the lowest expected temperature. Moderate oversizing in watts is fine, but voltage must never exceed the limit.
Connect the battery first, then the PV array, then the load. Install a fuse or DC breaker within 6 inches (150 mm) of the battery positive terminal. AIMS lists 10 AWG wire. Mount the controller vertically indoors or in a protected enclosure with 4 inches (100 mm) of clearance above and below, never in a sealed battery compartment. Connect inverters directly to the battery.
Yes. Select LiFePO4 or Li(NiCoMn)O2 before you start, since the default is sealed/AGM. Battery reverse polarity protection excludes lithium, so always check polarity.
No. The enclosure is IP30 and conformal coated. Install it indoors or in a protected enclosure.
AIMS gives this controller a 2-year warranty from the date of purchase. Reverse polarity damage isn't covered.
The AIMS Power 30 Amp MPPT Solar Charge Controller pairs up to 100V of PV input with 30A charging, lithium profiles and a conformal coated metal case. If you'd like help sizing a series string for it, the Outbound Power team is happy to help.
