FEATURED SOLAR DISCONNECT SWITCHES AND CONNECTORS
AIMS Power Solar PV DC Quick Disconnect Switch 1200V 32 Amps
A single string isolation switch with MC4 connectors, sized for most residential and small commercial solar installations.
- Best For: Cabins, vacation homes, and single string rooftop solar setups
- Output: one 32 amp circuit rated up to 1200 volts DC
- Two pole design opens both the positive and negative wires and suppresses the arc in under 5 milliseconds
- Outdoor rated, waterproof, and non-corrosive with UV resistance to UL 746C, backed by a 3-year defect warranty and lifetime tech support
AIMS Power Solar PV DC Quick Disconnect Switch 1600V 64 Amps, ETL Listed to UL Standards
A two string disconnect with separate MC4 connectors on each circuit, built for higher voltage strings on larger PV systems.
- Best For: Two string arrays, commercial photovoltaic systems, and jobs where code calls for a listed PV disconnect
- Output: Two 32 amp circuits, 64 amps total, rated up to 1600 volts DC
- Four poles isolate both conductors on each string, in a weather-resistant enclosure measuring 7 by 7 by 4.375 inches
- CE, TUV, SAA, IEC, and UL certified, RoHS compliant, and rated for ambient temperature between -40 and 70 degrees C
MC4 Compatible Branch Connectors, MMF and FFM Pair
A 2 to 1 branch connector pair for joining two panel leads into a single run, so a small solar array can be wired in parallel without a combiner box.
- Best For: Two panel parallel wiring on RV, van, and small off-grid setups
- Includes: the MMF for one side of the circuit and the FFM for the other, since parallel wiring needs both
- Â MC4 compatible ends mate with standard photovoltaic panels and solar PV wire
- Keeps the connection sealed at the splice point, so the run stays weatherproof
APPLICATIONS
Build a Solar System
Solar
Installers
Meet the NEC disconnect requirement on every job and leave service crews a clear cutoff at the array.
RV Manufacturers and Dealers
Give owners a labeled isolation switch so roof panels can be shut off before anyone works inside the coach.
Work Trucks and Fleet Vehicles
Add a disconnect point ahead of the controller so a truck can go in for service without pulling wire.
OEMs and Upfitters
Spec a listed disconnect into the build at volume pricing, and work through enclosure placement and wire entry gland sizing with our engineers.
BUS & VAN MANUFACTURERS AND OPERATORS
Put emergency shutdown for roof mounted solar within reach of the driver or the service bay.Â

COMMON QUESTIONS
Frequently Asked Questions
In most permitted installations, yes. The NEC requires a means of disconnecting a photovoltaic system from its conductors, and many jurisdictions require a readily accessible DC disconnect at the array. Even where code does not force it, a separate switch lets you kill the array before touching the controller or inverter.
Match the switch to the string rather than the panel count. Add the open circuit voltage of every panel in the string for your voltage figure, apply NEC derating to the short circuit current for your amp figure, then pick a switch rated above both. If the array is not designed yet, our solar sizing calculator sizes the system from your load first, and the string figures follow from there.Â
No. A disconnect switch is an isolation device that opens the circuit when you throw it. A circuit breaker or fuse holder is overcurrent protection that trips on a fault. A PV system usually needs both, often with the breaker sitting in a combiner box and the switch between the array and the controller.
A solar disconnect switch belongs between the solar array and whatever it feeds, so the charge controller, string inverter, or battery bank can be isolated while the panels stay energized. Put it where a service tech can reach it, out of direct sun, and check your local code, since many jurisdictions require the DC disconnect to be readily accessible.
No. These are DC disconnect switches built for the higher arc energy of direct current, which is why the arc suppression spec is measured in milliseconds. An AC disconnect for the output side of a grid-tie inverter is a different device with a different rating.
