Thanks for the link to "your story" @wattmatters . I'll enjoy reading that.
This reply is a bit late and out of sync with my other posts, but I'm learning as I go here.You need to talk with some who knows Australian Law. We can tell you how but I have heard it’s no joke to mess with that stuff there.
Don’t known the inverter but it’s doubtful.This reply is a bit late and out of sync with my other posts, but I'm learning as I go here.
I'd like to use the inverter offgrid, so I don't think the law will be a problem, but it was orginally used with 8 36 volt panels connected in series, producing a total of 288v. I want to use it with a 24 volt battery. So even if I could get it to work offgrid, which it is not designed to do, would it work with such a low input voltage?
If you mean the Fronius Primo inverter then it cannot operate on its own as an off-grid inverter. It is a grid following inverter only, IOW it needs a grid power signal to operate.I'd like to use the inverter offgrid
Thanks for the reply. I was pretty well resigned to an answer like that.If you mean the Fronius Primo inverter then it cannot operate on its own as an off-grid inverter. It is a grid following inverter only, IOW it needs a grid power signal to operate.
Not that I'm aware of. Normally you buy a 12, 24 or 48 V system.But on a smaller scale, do most brands let you adjust the input voltage?
I've no experience with such inverters. But I would expect most will have a fixed DC input voltage. There will be variable voltage inverters but at what cost?I've been looking at reviews on the XIJIA SwiPower 3kW Inverter, and it certainly looks as if the input voltage is fixed. Any thoughts?
Thanks again.Not that I'm aware of. Normally you buy a 12, 24 or 48 V system.
I would be starting with a power and energy audit. That will guide you on the inverter and battery voltage requirement.
Anyway, from what you say, it looks like I should dive straight in with the 24v 8kwh system.
I never understand why people in houses consider anything but 48V.Anyway, from what you say, it looks like I should dive straight in with the 24v 8kwh system.
That's the energy part of a power and energy audit.
What about the power side? 24V systems are typically rated max of 3 kW continuous. Is 3 kW going to cover your power demand at times?
In short, because this is all new to me and I don't want to sink too much money without getting a personal feel for how robust and long lasting these batteries are. I'm not powering the whole house 24/7. I just want to test the feasibility of going offgrid for a few hours each day during the peak rate period. If the economics don't work out for the peak rate period, it is a waste of money buying enough capacity for 24 hour cover.I never understand why people in houses consider anything but 48V.
12V is for mobile homes/vans/campers.
My chest freezer pulls 1000W when the compressor starts, then drops to 100W.. I think the max power when starting the motors would be around 200w, momentarily pulling another 8 amps each.
Good info, thanks. I'll need to monitor that.My chest freezer pulls 1000W when the compressor starts, then drops to 100W.
Yeah that can be problematic.I just want to test the feasibility of going offgrid for a few hours each day during the peak rate period.
Depends on the house depends on the locale depends on the person.never understand why people in houses consider anything but 48V.
12V is for mobile homes/vans/campers.
Good logic. If it ROIs reasonably well it is worth it and a convenient backup system is in place.If the economics don't work out for the peak rate period, it is a waste of money buying enough capacity for 24 hour cover
Surprised she isn't still using gaslights.Depends on the house depends on the locale depends on the person.
My lawyer’s been 12V solar going back 20 years. Her home is not mobil, isn’t a van, and is a wood framed house a couple miles from the nearest powerco pole. I guess she didn’t get the brief?
I think she has some for backup.Surprised she isn't still using gaslights.
More to do with me being cheap.But I’m interpreting your comments as a bit snobby on the teacup tipping.
