510C Pro/Tran2 50-Amp 10-Circuit 2 Manual Transfer Switch with Watt Meters

Well-made unit easy to install wiring could be a little bit longer switches operate smooth no problems, transferring between commercial power and generator

Easy install and fairly roomy during wiring. Designed with attention to detail. Works with my generator for selecting critical loads.

Arrived when promised and works great.

Works awesome got it wired in when we didn’t have power for a week

OK! We have 10 kw of on-grid solar (12.48 kw of panels). I wanted to do more: 1) Because my provider is a municipality unregulated by the utilities commission and plays some pretty dirty tricks, but I digress. 2) To decrease CO2 and do my part toward mitigating climate change, of course. 3) to be able to turn on the porch lights and go wave at the neighbors during the rather notoriously frequent power outages my provider provides.There was no way they were going to let me install more solar; I knew better than to even try. So I got off grid solar - it doesn't touch the grid at all - ever. LiFePO batteries, 6.8kw, 48v inverter, Classic 150 charge controller, and this thing. They can't tell me I can't have it. It's none of their business; I'm not part of their business (Pun intended)This thing, I thought, was perfect, and I was right. It's mounted on a cinder block wall, about eye level high, and all ten circuits are wired into a 200 amp main breaker panel in a 3000 sq ft building with 10 foot ceilings. The ganged breakers farthest left do the water pump. The next ganged breakers do pretty much all the (LED) ceiling lights in the building. And then, the kitchen, the living room, the computer room, like that, until all 10 circuits were used up. I thought that if I used two of them for the water heater, I'd regret it. That thing's 5500 watts and who needs that, leaving only 1300 watts for anything else during a power outage when there would be hot water for a day or two in any case, depending on usage. I wanted to do the (4 ton) heat pump. That takes about 3500 watts and would have worked, except the inverter couldn't get it started and we aborted. It probably takes something like 50 or 60 amps as it's starting. The furnace (with a forced air blower) IS wired in, though! The furnace is dual fuel, the heat pump backed up with natural gas. So there is almost NOTHING we can't do off-grid!Here's the fun part: In Nov and Dec, there really isn't much sun! There's really only good sun for 5 or 6 hours. There are rainy, overcast days, especially thanks to climate change. The panels will, sooner or later get covered with snow, at some point. I can tweak and fine-tune the load so there's never any solar going to waste or, on the other hand, discharging the really expensive batteries below 20%, which will decrease their lifespan (~25+ years). I love the fine control. If we didn't make anything much on a given day, I put the refrigerators, freezer, furnace, etc on-grid and leave the rest off grid. If the batteries are in good shape, everything goes off-grid! (Which causes the on-grid solar to send the Township relatively massive amounts of electricity.) No water heater, no electric car quick charging, no heat pump. That's about it!I like it a lot! On the one hand, there's nothing unnecessary in it. The wire sizes are just what they need to be, not a bit more. On the other hand, the box is extremely well-made and well thought out and I have no complaints. It could have been a hair better for me if it had more 20 amp breakers because my main panel has mostly 20 amp breakers. But the breakers can be easily switched out, easily ganged, easily un-ganged, etc. I also wish there was a 12 circuit option. The 10 circuits in this got used up quickly.The really nice thing, with this box, is that if you move the switch in a firm, swift, accurate motion, it'll go right through the center off position to either on-grid (line) or to off-grid (gen - aka solar) IN ALMOST NO TIME!! This is great. I'm typing to you off-grid right now. I guarantee you I could switch the computer room from off-grid to on-grid and back 10 times without crashing a thing in here. All the usual internet stuff, two computers, 3 NAS's and more. Same with the kitchen. A very short power outage nukes the clock on the microwave. I could switch back and forth all day (or until my fingers get tired) and not nuke that clock! That was actually kind of unexpected! I don't know how they did it, but I'm sure that quick switching was no accident, some thought appears to have gone into the design. Lastly, everything electrical costs a small fortune. With that in mind, this is a very solid deal for the price and it's unique to the point where the solar installer, on the phone, informed me there was no such thing, when I was telling him what I wanted and describing this thing on the phone. It's actually intended for generator backup, and it will, of course, work equally well | just the same for that.The meters have rings that go around the wires - it operates in much the same way as a clamp meter. The wires for the circuits are in some big, flexible conduit that take them to the main breaker panel. They're labelled. one color goes to the breaker. The other color wire gets wire-nutted to the wire that was on the breaker. This is true for all 10 circuits. The two wires hanging in the bottom of the transfer panel get connected to the aux input - in my case, solar, normally a generator.

Well design Electrical Panel for Home/Small office back up system equipped with transfer switches Circuit breakers and two electrical meters. Very easy to install and control with some basic electrical knowledge

Ok so you want to tie your generator or in my case an inverter to your home. This is an easy way to solve that problem. It is a very good quality poduct that will give you 10 circuits to tie into your home even if you have never done anything like this before. They have videos on line that make it so simple almost anyone can do it. A bit expensive but it works. The only complaint I have is the wires are not long enough even when installed right next to your circuit breaker box.

It has been raining and I am still waiting for a generator. So how can I rate it? Check back in 90 days.
