The AIMS Power 30 Amp PWM Solar Charge Controller (SCC30APWM) sits between your solar panels and your battery bank and turns changing PV power into steady three-stage charging at up to 30A. AIMS rates it for up to 400 watts of solar on a 12V system and 800 watts on a 24V system.
It's made for RVs, vans, cabins, garages and other small off-grid systems. The 1 lb housing has mounting flanges and molded red and black terminals that help prevent reversed polarity, plus a DC load port and USB output.
It charges in bulk, boost and float stages and runs a two-hour boost when the battery drops below 12.6V. Temperature compensation is -24 mV/°C on 12V, doubled for 24V.
Choose sealed (the default), gel, flooded, LiFePO4, Li(NiCoMn)O2 or a user setting. AIMS also lists AGM batteries as compatible. Float, boost and low voltage points are adjustable with the two front buttons.
The display cycles through battery voltage, PV voltage, charging current, discharging current and battery temperature every 3 seconds. A working record counts low voltage events, over current events and full charges.
The load port supplies up to 30A to DC loads, 24 hours a day by default or after sunset for a set number of hours in light and timer modes. It shuts off at the low voltage disconnect point to protect the battery. A USB port supplies 5VDC/1A with short circuit protection.
Protections cover PV short circuit and reverse polarity, night reverse charging, battery reverse polarity, battery over voltage and over discharge, and load overload and short circuit. Above 85°C inside, the controller stops and restarts once it cools below 65°C.
RVs and vans. Keep a 12V or 24V house battery charged from roof panels.
Cabins and garages. Run a small off-grid system with DC lights on the load port.
Solar lighting. Use timer control to turn DC lights on after sunset and off after a set number of hours.
A PWM controller like the SCC30APWM needs panel voltage matched to battery voltage, which keeps the system simple. An MPPT controller converts higher panel voltage into charging current, so it suits larger, higher voltage arrays.
Loads on the load port shut off at the low voltage disconnect point. Loads wired directly to the battery don't, and can keep draining it. Inverters always go directly to the battery, never on the load port.
Maximum PV open circuit voltage is 27.5V on 12V and 55V on 24V. AIMS's sizing table pairs a 12V battery with one 36-cell panel (Voc under 23V) per string. For 24V, use two 36-cell panels in series or one 60-cell (Voc under 38V) or 72-cell (Voc under 46V) panel.
Connect the battery first and wait for the LCD, then the PV array, then the load. Fit the battery fuse on the positive terminal within 6 inches of the battery, and add breakers or fuses to the solar, battery and load lines.
Yes. It has LiFePO4 and Li(NiCoMn)O2 settings. With lithium, if the PV is connected and the battery is reversed, the controller will be damaged, so check polarity first.
Yes. On 12V, float is 13.8V (13V to 15V), boost is 14.4V (13V to 17V), low voltage disconnect is 11.0V (9V to 12V) and reconnect is 12.6V (11V to 13.5V). Values double for 24V.
It reads it from the battery, so connect the battery before the panels. The battery needs at least 8V for the controller to start.
The AIMS Power 30 Amp PWM Solar Charge Controller combines three-stage charging, lithium settings, a 30A DC load port and USB output in a 1 lb housing. If you'd like help sizing panels for it, the Outbound Power team is happy to help.
