Ok then PM me the information. That is not self promotion or advertising since I asked for it.Yes, you are right!
I've run a standard 120 volt water heater on 48 volts DC and it worked fine, albeit a bit slower.You do NOT actually run off DC, you use an Inverter to give you VAC ! Only a total git would try to run an AC device using DC Power.
What is your primary Demographic for this heater?Have a check. I have deleted my email add. So it is not an advertising.
Yes please. ThxOk then PM me the information. That is not self promotion or advertising since I asked for it.

So you recommend this or heat pump hot water heater?I heat all my hot water at camp with excess PV. Small tanks tend to be as expensive as big ones. I have found you can get BOSCH ES4 4 gallon water heaters on ebay for $48 shipped. I just got one, it was brand new and just an open box someone had brought back. These have good insulation. I also have a 40 gallon tank for my laundry. These tall tanks easily stratify and the top 15 gallons heats easily and the lower section is preheat. Here is a camp setup with only 600W of panels and it has enough excess to heat water. It operates in parallel with charge controller, but uses no power from controller or batteries. They are always left fully charged. Nobody else knows how to heat water on this board.
Heat pump is the best heating of stored power, excess for dump load is great as well, if you frequently have excess solarSo you recommend this or heat pump hot water heater?
Actually direct solar to heat pump is the best, but no one makes them.Electeic Instantaneous water heaters are extreme energy hogs... even if you put one on each sink and shower, the small ones pull tons of watts.
A tank style heat pump water heater is the most efficient electric type, direct solar would be better...
There is fridge on this principle of work.Actually direct solar to heat pump is the best, but no one makes them.
I had to build my own 1 ton unit.
The efficiency of a direct solar panel decreases as water temperature increases.
So I run it on the cool side and pump the heat into another loop that transfers the heat into a solar hot water tank.
I use a water to water heat pump. It is much more efficient and more easily adapts to existing solar hot water panels and to solar hot water tanks that use water to water heat transfer.There is fridge on this principle of work.
No problem to invert process from cooling to heating.
Combinate it with Fancoil cooling/heating system.
There is no single answer. With a really big system a heat pump is just an additional load on the system. Typically figure an additional 1KWH expansion of battery. HPWH are not a suitable dump load as the draw is pretty load. Rather than just waste possible energy it can be dumped into resistance in large amounts and rapidly. I have a HPWH supplemented by PV resistive.So you recommend this or heat pump hot water heater?
