We were invited for a Raclette lunch at a friend’s place yesterday. They had a solar/AC powered battery that they used to power the raclette oven. Provided power for almost an hour. Apparently it had charged up to 100% on a sunny day last week. They can also charge it from mains.
I asked them if it could be used, in event of a power cut, to feed power back into the house power. Not to use to power a ralette oven but to keep our heat pump circulation going. They weren’t sure.
The specifications say 1x AC output. Am I being naïve in thinking this could work?
If you can isolate the power for the heating system to power it directly, it would be possible, but you need to check the specs of the device. Most critical is the inverter part and whether it is a pure sinewave inverter and has sufficient rating to drive the inductive load for the motors.
So if I turned off the circuit breakers for everything except the PAC that could work? I’m not certain of the power needs of the PAC, so I would need to check that.
am always encouraged, not, by how individual efforts to conserve consumption on the domestic front are actually driven by commercial encouragement to consume.
Migros has the new coffee system, which requires a new machine...compostable capsules in the “vintage” form have existed for some time
You need to also isolate from the grid network. Unless your heating is outrageously powerful, I expect it should be fine - don't expect it to last too long with such a small battery though.
Looking through the instructions, it's more of an EPS for a single device which would normally have an AC plug.
You would plug the EPS into the mains (via the charging cable) and then plug your appliance into the EPS.
Your heat pump probably doesn't come with a plug so you'd need to do a bit of wiring but in theory, providing the EPS can provide enough power, it should work.
Do be honest though, if heating is turned off in a house, it will stay warm for a few days* so for an extended power outage, I'd be more concerned about my fridge and freezer.
Looking into this a bit more, it would appear that people who have solar/battery solutions want the battery backup for everything, except the heat pump!
I'm looking into backup power for: oil heater and fridge/freezer (also lighting).
As you say, batteries are only useful for short term power cuts and for those, heating and fridge/freezer can live without power for a few hours. For longer term power outages, you'll need to consider power generation e.g. solar panels, generator etc.
I have a small, 3kW generator for such situations... and about 300liters of bioethanol just in case for heating. Sadly, I don't have a wood stove - but been looking at one.
It's 1.7k mate. It doesn't make any sense ... Unless you are severely disabled and need to power some kind of medical device or something that your life may depend on...
Or maybe you really, really, really, really want to show off at a raclette and have more money than brains
