how many amp service is needed for the tempra 29 plus

The answer to that of course depends on the other loads on the system and would be different for each location and user. Mine is a 200 amp service. I also have an electric heat pump/ac. I would consider our family a moderate to heavy power user. (lots of devices and appliances operating at the same time) I have not had any issues with power.

200 amp is the minimum. It does draw a lot of current - the lights on our christmas tree dim when the hot water is used.

1 Amp. I would not buy this item if you plan to use it more than once. I kept it well ventilated and ran it under the usage rating but it still quit working after a month. Waste of money, spend a little more and get something better.

I can only answer you from a electrical standpoint. At 24 kW and 240volts, you would draw 100 amps of current. You would need an electrical panel capable of handling 200 amps, if these were the only 2 circuits. If you installed two of these tankless heaters in addition to the rest of the house, you would need more than 200amp service. Larger than 200amp is possible, but not common in a residential situation.

take a 30amp. main breaker on input side and a combination of up to 30 amps on the out put.

You don't need another 30 amp controller. 2 more panels would only put you at 28 amps, and I've never seen a panel that puts out its advertised amperage anyway.

A typical domestic water heater is 4500W for each element at 240V, but only one element is allowed to come on at a time. So that's 4500/240 = 18.75 amps. Even with a 10% or 20% margin, this Aube timer - rated at 30 amps - is more than sufficient. This item allows 7 programs. So you could have a different schedule of 1-off/1-on on 7 different days, or you could have 7 identical on-off cycles for all days. One of the beauties of this unit that distinguishes it from the others (including Intermatic digital timers) is that you can install an external SPST switch (a basic light switch will work fine) which overrides the unit and puts it into manual or switches it back into automatic. So, for example, I can use the switch to put the water heater into manual mode and leave it off when I go on vacation. Then, I leave instructions for my house-sitter to just throw the switch and put it back into automatic mode on her last visit so we have hot water when we get home from the airport.

You will have to run cold water to the tank...you also need a dedicated 30 amp breaker to operate.

Make certain that your circuit breaker has adequate amp to operate the heater

A 30A Charge controller WILL be adequate and will work but it is a narrow margin for your 145 watt panels. I estimated the amperage on your panels @ 7.25 amps each, that put you right at 29 amps. Barring any solar fluxes that might tip the controller to temp shut down you should be ok.

I know you looked at there website, try to find the contact number. I do not know either. I have two and so far they work good, can't run an air conditioner without issues, I think I need more amps to get the 10,000 (so they say) watts. sorry I can't help much.

It recommended that it be a 20 amp. As to whether that has to be dedicated or not, I don't know, but I know that on my breaker, it is on its own circuit. I think the heater takes a fair amount of energy so it should be on its own.

The unit is well built. I'm running it as 30A per fuse with no troubles. If it were total that would be less than 5a per fuse which is pretty useless.

I pull at least 40 amps through mine 24/7 during winter. Large instant water heater. To heat a detached garage floor. Works great!

I've used mine on job sites but you need a dedicated 29 Amp circuit for it.If your converting power and need an inverter I'd try to find a compressor that dies not draw so many amps cayse it will take quite a bit of start up amps from your power source

You only need about 30 watts. 30 watts divided by 12 volts is 2.5 amps of 12 volt DC power.

Since you are in CA, it probably would be fine unless it gets really cold in the winter. That said, since you have 2 60 amp breakers already installed to the location, why not be safe and use a bigger Stiebel Eltron (SE) that specifies 2 60 amp breakers. You can use less than your breakers can handle but never more. Without going to the trouble of looking up the various SEs, I think you would be better off with a SE tempra 28+ (+ if they make that version) IMHO.

I really don't know how many amps it requires. It sit on my kitchen counter, does not take up a lot of room and although not fancy it does the required job. I live in an apartment.
