The ATS is 200A and transfers the whole load. But 20kW is only about 80A. How do you restrict the load but not when on street power?
2035466
There is no restricting the load. If you are looking to make sure that you can not draw more than the unit can put out the way to go is the select circuit transfer panel. This will allow assigning of specific circuits to assure the proper load for the generator. If you should have any questions please feel free to contact me at 800.654.7440 ext 109.

I have an all electric home and the unit powers everything except my 70KVA heating system. I cut one breaker on the system to make it a 35KVA and it works fine. It powers my 4 ton central air, refrigerator, electric hot water heater as well as three burners on my electric stove. The amount of electricity used for lighting is insignificant since I have changed to all LED bulbs. Do no fear overloading the generator because it has a breaker to prevent damage from overloading. I had the local Generac dealer install mine and he tested it with the above load and it was only using 60% of its rated output.

Adam, I think what others have said is what I understand to be the case. The transfer switch, in our installation, transfers the power from the geneator to a separate panel which contains the circuits in our house that we want during a power outage. We we are on the grid, that panel is still functioning but the transfer swithch isolates it so thoes circuits contiune to be live. There is also a load sheading aspect of the switch that depowers selected circuits if the load is approaching the rated limit--things like airconditing units. Hope this helps.

Don't understand your question completely, but when you are on "street power" this unit is just sitting there doing nothing and your normal electrical panel is totally engaged. We installed this at my house with a second panel and circuit breakers for what I wanted to run when the power goes out. It is not the whole house, but I know of people who can power their whole house with this. Not sure if that helps or not.

It is about 80A at 240V and 160A at 120V. It is not large enough to handle our whole house if the wrong combination of loads are on at power loss. So, if we are home the generator would not be able to start. We would shed large loads (water heater, oven, dryer, heat pump, etc) and start manually. When we leave town we turn off the water heater and one heat pump so the load is not too large. Have only had a few power losses and no problems so for.

Thank you for your response I ended up ordering a product from AST for $141.00 that will run off my 240VDC low voltage garage opening system no need for a separate 115V outlet as well. Note: If anyone has anything valuable in or garage you need to have an auto-lock system.

Can't answer as I sent unit back right away as soon as I read don't use if engine is on - and that's the only way my power outlet have power.

It depends on the lamps you are driving with the controller. This controller is capable of up to 6A per channel, so yes if you were driving enough lamps to max out the controller it would require an 18A power supply. This controller and an 18A, 12V power supply can drive up to 216 W(atts) of lamps.

It must not exceed 140 to 150 watts based on a 20 amp watt fuse rating in your vehicle.

If you are using 4 panels with this kit it only uses a 20 amp controller. You must be using a 24v battery bank to use up to 400 watts. Can you explain your situation a little more? We are a bit confused with what setup you have. Thank you. AW

Hi, the output is limited to whatever the input power is. Example: 12 volts @ 20 amps is 240watts total available power. If you convert it to 24 volts, you only have 10 amp outpue minus whatever the conversion draws. You can't get power out of things air. Make sure to use additional heatsinks as these are rated 150 watts max. Good luck!!

You may be using too small of a circuit, or a circuit that doesnt have enough excess capacity based on its current load. Try a different circuit.
1844047
Check the capacity of the circuit you have it plugged into. This needs to be on a 20A circuit as it will draw up to 17A, depending on your power supply. That is, BY ITSELF on a 20A circuit.The MINIMUM current draw will be 15A and that is already too much for a 15A circuit, you will likely blow the circuit. If it doesn't blow the circuit as soon as you plug it into a 15A circuit (and turn it on), there is something wrong with your wiring.

And to add to Clark's formula. If your alternator is up to 15 volts. That is 208 amps for 2000 watts of inverter power. Note: Your alternator better be a huge one to handle those loads.Rule of thumb for inverters. It will draw 1 amp for ever 10 watts. so 2000 watts is 200 amps. If your inverter has continuous rating of 2000 watts with a surge of 4000 you need 400 amp fuse and wire like 2/0 gauge OFC (Oxygen Free Copper). I would suggest staying away from the copper clad (CCA) cables at these power levels.

In my car I'm running a shunt between the alternator and the negative terminal to read the amps, the power was tapped from a cigarette lighter wire. I believe running the tiny power wires to the shunt would fry them when cranking.

One that will transfer 30 amps of power and break it down into about 8 to 10 curkits in your existing main pannel with a manual transfer switch But you will need to shut the main in your existing pannel off befor turning on the auxillery pannel. I think Amazon sells the auzillery pannels also, hope this helps. Milt

put a active wire,off the drok dc meter, to the active line being used to, run things in your rv that should use of power and what is left good luck Chris

Hello,If you are charging 12v nominal battery bank you can input up to 400 watts of solar power.If you are charging 24v nominal battery bank you can input up to 800 watts of solar power.The wiring configuration of the 800 watt panel setup must be done so that you do not parallel all of them or not series all of them or else the panels will either go out of the 100 VDC or the 40A rating.The 800 watt setup must be wiring in series/parallel.Please let us now if you have any further questions.Regards,AW

It doesn't matter how many watts are available on the input, what matters is the load you have connected to the output. As long as the load attached to each circuit does not exceed the rating (of that circuit, i.e. 10amps, 20amps, whatever the rating is) there will be no problem. When you are switched to the mains side, it is capable of supplying much more than 8Kw and the power will be passing through the same circuits.

"Wattage" is normally shown as "Max" wattage when in operation. If this product is listed as .8 watts (120vac x .067ma) then the "idle" current should be significantly less, probably about .020 amps/20ma or 120*.02= 2.4 watts. It could easily be less, depending on the circuit design. When the lights are not on, the unit is 1)determining if it is light or dark (dusk to dawn sensing) and 2)if there is "motion" in the vicinity. The energy used during this "idle" process is extremely low.

would be great to have an answer for you; I feel that is best answered by someone who knows wiring and current loads...I don't.
