I'm going to go off grid for a little while and going to be dependent on a battery - inverter combo for power.
Anybody have any suggestions as to the inverters that will produce the cleanest power for audio? I'm looking at a full sine wave inverter that will manage around 5amps. There are multiple manufacturers though, and now I'm trying to figure out which to purchase.
I'll more than likely be buying a couple of lead acid deep cycle batteries to run the inverter off. I have looked at LI but I'm not sure if they are a good option considering cost vs, benefit.
Thanks
Paul

In another week I should be able to tell you what I think about this inverter:

I've had grid tie for about 12 years, and am now putting an off grid system together to run office, pool and garage. My guess is going to be that most of these inverters aren't any worse with regards to noise as all of the electronics, motors etc., we have in our homes that will plug into it.
With regards to battery, I bought a lithium ion, and would only recommend it if you can keep it cool. It is very hot here in the summers and have gutted a heatpump, leaving the evaporator coil, to store and cool the battery by circulating cool water through the evaporator coil.
I am using a Raspberry Pi to control it, monitoring the battery level, when drop below certain thresholds it turns off things that impact me the least, starting with pool pump, garage AC...
Lead acid batteries will be fine, just make sure to vent them. I've fooled with different battery types for electric bikes and hybrid vehicles. A lot of people re-purpose EV batteries, which is a good idea, but the prices are up. I would not recommend NiMH they don't do well unless you keep them within a fairly narrow charge range.
Ok, what can you tell me? :-)
I just went live with it about 10 minutes ago. One thing that is great, is I have vintage equipment and it all synced to the inverter at 223V so 112V volts per leg, which is what the equipment was designed for. As far as noise, I can't immediately hear any difference, but I do have a Furman line conditioner that the audio equipment plugs into.
Great to hear. Well I hope you enjoy your new setup. Please give me some feedback once you get enough listening time in.
I give myself several days of listening before I make judgement to eliminate the effects of novelty and other short term influences like mood.
Regards
