I have been researching the topic for awhile and been reading other forums about it. I decided to get enphase battery mainly since it’s newer and I like the design of it. But It had humming on some equipment . So I thought the popular ecoflow delta 3 plus that other forums high recommend would be better and got that.
What I noticed is the EcoFlow isn’t as good as the enphase. Both are silent while in use at low loads. They both do have a high pitch whine to them if you listen carefully. I think the EcoFlow is noisier since it has 1 large inverter while enphase uses 3x of their micoinverter. 2 are on idle while only 1 is in use at low loads. My floors are tiled so I can hear the high pitch from them sometimes at few feet away.
Downside I noticed that no one posted about is both units create dc offset and make many of my equipment with linear psu hum. Maybe in other forums they were using speakers and further away and don’t notice it.
The Innuos pulsar and zahl hm1 hum a lot, like buzzing. While wa24 and cavalli liquid glass hum mildly. I contacted enphase about this and their engineers wanted to figure out why. They sent me an ifi dc blocker. While it helped a lot. It didn’t fully get rid of hum on some. I tried with EcoFlow too and it also helped the hum. Innuos pulsar seemed to react best to the dc block and is silent after. Zahl,wa24 still had some humming if listen carefully. But a big improvement.
I was able to borrow a puritan 156 which also has dc block and it does the same as the ifi.
Next thing is switching noise. I have a device from Japan that blocks noise and converts some to light by blinking. Usually at home outlet, it blinks like 1-2 times a second. When my family is using the hairdryer or room heater it goes crazy and blinks rapidly. On the enphase it’s quite good and blinks like once in 2 seconds and with the puritan it pretty much doesn’t blink. Sometimes once per like 8 or more seconds. But on the ecoflow with the dc blocker, the light is just solid on. Never seen it like that ever. Even with the purtian on the ecoflow the light would just be on. Guess it can’t filter out all the high frequency switching it’s doing.
The ecoflow app has more features like setting schedules and offline mode while power cable still connected. Enphase app looks better and has much more details on what each inverter is doing and power stats. It’s a new product that launched recently so it’s still missing many features.
I have 33 of same enphase inverters on my roof plus tons of electronics at home, Ev, led bulbs, etc. So enphase battery with 1 inverter and 2 idle seem like it would be much less noise.
How they compare. Honestly I don’t remember. I stopped using the ecoflow delta 3 plus pretty early even though it seemed highly rated on other forums. On the enphase+ dc block, from memory few months ago, I noticed blacker backgrounds, more bass, better separation, depth and details. I just used one of those switches on the power cable and turn off the power to unit when I want to use my audio stuff. Both have that ups feature and instantly switch over to battery.
Sadly overseas now and won’t be any to test anything for awhile.
Edit: while dedicated lines help. Noise from neighbors and own house still goes into that dedicated line. I tried the Japanese blinking noise blocking device on rooms with nothing plugged in and it blinks at the same rate as all the other rooms.
