Re: Price of kebab....
I'm also interested, I have a small set up already, but I would be interested to know the makes / models that you have installed. I was looking at sunpower equipment, but 8 x 400w panels instead.

Re: Price of kebab....
The panels:. Trina Solar.
The Inverter: Voltronic Power. The Model: Axpert 5kva 48v VMIII The battery: Pylontech 48v 2.4kw NOTES Panels The key to purchasing second hand panels is the supplier warrants the amps. Mine did and still does at 95% of the rated amps. I tested all on arrival and all met this with many exceeding the rated amps. Inverter 1. Voltronic Power are a ODM. In other words they design and make them but do not sell them under their own name. You will however find their products online in Spain just by typing in Axpert and or voltronic inverter. Many of the well known inverter brands in Spain are also Voltronic units. For example masterbattery as sold at Leroys, Solix autosolar etc. ​​​​​​2. The Inverter I purchased was specifically for my needs. They have loads of versions available. It is important to choose the right one. Battery Pylontech are an OEM. They brand under their own name and many distributers and retailers sell them under their names. The battery I list is the 2.4 KW 48v version. Being a LiFePO4 battery it has a DoD of at least 90%. General I posted my original reply and my setup based on the poster already having a grid supply. They are in heaven because with my set up they will slash their costs and still have 24/7/365 power. For those totally offgrid, like me, my setup is great BUT : To get anywhere near 24/7/365 power in the average house without the generator firing up requires far more batteries than I have and or sensible planning..... ​ Best Loco

Re: Price of kebab....
How practical would it be for a high demand, such as over 10kw? Presumably that would be quite expensive.

Are you talking Constant or Peak ? Based on your post above ( I think 56 ) you must be connected to the grid . If so the type of system I listed will save you a fortune but given your usage the inverter should probably be higher. ​​​​​​Do you have an idea what the maximum load at any one point may be ?

Re: Price of kebab....
Fred,
I just checked. In the same range/type of my inverter Voltronic Power offer an inverter that offers 8kva Constant and 16Kva peak with PV max input being 2 X 4000W. The cost is less than 1400 euros inc IVA and delivery so no it is not expensive. As for is it practical ? Yes if you have the roof or land space to mount the required number of solar panels.

That's my issue. I don't have a generator and don't want one if I can help it, I'm totally off grid, the nearest mains connection is impractical/long way away, and would cost I was told around 40,000 Euros, and that's only if the owner of the land the nearest pylon is on would give permission for us to cross his land and somehow string up a cable to it - which when we asked twelve years ago said no. So we have a battery bank of twelve 2V tall and slim ones, like - https://renew.org.au/wp-content/uplo...02/web-4-8.jpg They give us in theory 3 days of power for rainy days and we have the usual washing machine but only use cold water, but also toaster, sandwich maker, hairdryer etc etc. Mostly short time higher power usage. In the winter it does get touch and go as to if we have enough capacity as the batteries are now twelve years old. I think the technology has moved on quite a lot since my set up was 'set up' and batteries, invertor and panels may need upgrading. Thanks for all the details you've mentioned and I'll look closely in to that. |

Re: Price of kebab....
You'll never run electric heating off batteries to be viable surely.
No matter the battery power needed, the panels to recharge them. |
Re: Price of kebab....
I suspect you are right.

Re: Price of kebab....
I saw an advert for a company called campohelios.es and they were offering 5kw for €5.900(+iva) installed in one day.
I would assume 2 systems in parallel, and 2 sets of 10 535w panels, with the load split between them. These are grid tie systems, they do the paperwork too. It would greatly reduce your day time power use, with an outlay of around €14k ? But back to kebabs, ours in alhaurin have been around this price for ages I think ? It's been a while since I've had one |
Re: Price of kebab....
Well done! I am
From what you say and the pic you post you have a 24 volt system with lead

Re: Price of kebab....
Lead acid batteries, yes. 24V.

Mark, you have had your batteries for 12 years and they are still working well, you are to be congratulated !!!
​​​​Whatever the marketing claims, for instance designed for 20 years life, OPzS batteries require careful maintenance and always keeping the DoD to 50 to 60 % to last for anywhere near 20 years. I would be interested to know what amp hours your OPzS batteries are rated for and what DoD you have the charger set for. As for the tech moving on since your set up.... I am not so sure that in practice it has moved on that much except for lithium batteries. The prices for the kit have certainly moved on..... downwards.....and the capacity..... upwards.... thankfully for you and me and all off gridders. Best Loco ​​​​​

"I would be interested to know what amp hours your OPzS batteries are rated for....."
If you look at the chart in the following link, mine are "TYS 9" I believe. In more detail mine are Enersys 1.394 C100. They are not made any more, or at least not available, so if I wanted to replace like with like, I'd have to go down to a TYS 8 or up to a TYS 10. ".....what DoD you have the charger set for." I don't have it set for anything. The installers obviously set it so I don't have a clue. As I'd work on no more than I think 50% discharge for the batteries, maybe that's what it is. I can't really imagine with their construction it'd be more. Though I'd also guess it'd be rare the system lets them get below 25% before doing something about it. In other words, I have no idea - but I have to trust it's set right unless I find out how to check it. |
