AIMS Power carries solar disconnect switches rated up to 1600 volts and 64 amps, plus MC4 branch connectors for wiring panels in parallel. A solar disconnect switch gives you one point to cut DC power between the solar array and the charge controller, inverter, or battery bank, which is what allows safe service work and emergency shutdowns.
A single string isolation switch with MC4 connectors, sized for most residential and small commercial solar installations.
A two string disconnect with separate MC4 connectors on each circuit, built for higher voltage strings on larger PV systems.
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.
Meet the NEC disconnect requirement on every job and leave service crews a clear cutoff at the array.
Give owners a labeled isolation switch so roof panels can be shut off before anyone works inside the coach.
Add a disconnect point ahead of the controller so a truck can go in for service without pulling wire.
Spec a listed disconnect into the build at volume pricing, and work through enclosure placement and wire entry gland sizing with our engineers.
Put emergency shutdown for roof mounted solar within reach of the driver or the service bay.Â
My questions to Andrew were addressed in a timely manner, clearly and effectively to aid in the addition of an AC distribution panel in my van. My Aims inverter is a great asset along with stellar support!
Works well. Switches instantly. My TV is plugged into it and it never loses power.
AIMS power support team is so responsive, knowledgeable, and go above and beyond. They reply to my questions quickly either via phone call or e-mail.
They are absolutely exceptional.
AIMS Power offers solar products that support off-grid, backup power, and remote energy access applications. Choose compatible mounting hardware, solar panels, battery storage, inverters, and connection equipment for your solar installation.
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.
