Geyser timer solution for solar

Float? I thought lithium doesn’t float

It doesn’t, but you need to enter a number and that is the resting voltage value.

User defined needs a number .

It sounded specific when he told cavedog that’s why I was wondering

Anyone installed the CBI Astute Smart Controller ASC WiFi Enabled

Anyone know what the below means?

• Service life: 20 000 operations at full load

I installed two on my geysers. The one lasted about a year and the other one is two and a bit years old now.
I replaced the broken one with a sonoff POWR320D.

That is the specs of the relay. When you switch it under load there is some arcing and wear on the relay that eventually wears it out.

Guess you dont need to be a electrician to install it?

Any reason you went for the sonoff POWR320D over another CBI Astute?

Which sounds like a meaningless stat if yours failed in a year, switching off under load once a day is 54 years.

Technically you should be at least a wireman I believe as you will be replacing the isolator.

I flash most of my devices with Tasmota and the sonoff is just better supported for that. I wouldn't say one is better than the other.

Its the typical tests under perfect conditions but my failure was not the relay it was the electronics side of the board so doesn't apply in my case.

That isn't an isolator. You keep the existing isolator and add the switch before the isolator.

I have been running 2 x Astutes for my geysers in my DB at home since 2022. No issues.
Also have one on the pool/heatpump and one on another geyser at the holiday place.

Do you need both devices isolator as well or just the DB board WiFi piece?

Makes sense to keep isolator as that is last line of defence if this device fails and there is a short.

Sure any geyser has that already as I am sure there is one in my roof

I have the isolator one. But yes would depend on which you have.

Sorry I meant breaker in DB board that trips if overload or short.

I think the regularions dictates that a isolator has to be in place by the geyser

unless electricians just see it as good practice. , cause have never in my life seen a geyser without switch

The Sonoff could be fitted in place of the isolator, hence the comment I suspect.

Doesn’t have to be in the DB board like the Astute and bridged to the circuit breaker.

Does it not need to break both conductors? I am not sure all Sonoff's do that. I know the 320D manual states that it still needs a isolator with high current devices.

Yeah, regulations require isolator near device for when it needs to be worked on it’s easy to turn off. I think it’s quite a new regulation too because my house doesn’t have one. Breaker in the db protects cabling from melting in overload or shorting situations afaik.
