Great job. I have just been working on a battery bank with 1300ah still got to do a bit more work . Got a 10 battery bank. I now have 12v lighting in the house.
Interesting what you said about the cost of batteries. I went over to LiFePo4 cells about a year ago and I’d never go back to FLA. I recently built a 15kWh battery for 1500 euros. With the falling prices of LFP cells I could today build the same thing for little more than 1000 euros. Winter was alway a challenge as there are not enough solar hours in the day to fully charge FLA batteries. This is not a problem with LFP batteries. There is no lengthy absorbe period and it doesn’t matter if the LFP battery is not fully charged for weeks on end.
I have everything from Victron, and it will last for years. 1x inverter 24/800 230v 1x inverter 24/1200 230v 1x inverter 24/3000 230v. battery monitor, Cerbo-S GX central computer. I am very satisfied with Victron before I had Chinese junk
Someone once told me that , except you and I everything else was made in china. So, please be aware most of theb powerbords and components at least are made in china. Not all the stuffs are considered junk, if you're happy with the blue power that's a different thing. Cheers
Eveyone is pushing me to convert to lithium but for some reason and one of the reason was huge upfront cost I am still confidering lead acid or AGM. What i wanna know from you is that if those batteries can deliver the current you require for your inverter at a maximum load.
@@ferdm9646 Same here, many saying to me to convert to lithium constantly. The upfront cost is a big problem then there's the additional cost of the management units. Lead acid management units are much more basic and as such more reliable. This bank can deliver over 1000 amps if required however it's currently fused at 125 amps so as not to exceed the 3kw output of the inverter. When the 3kw unit is replaced for the 11kw 48v unit it will be required to supply 230amps max which won't be a problem as that draw would be less than a 1/4 of its max capability.
@@ourkilkennyhomestead2006 I was also told that this batteries won't deliver the current I need and it'll kill the battery soon , but 3kw at 48v will only draw about 62.5 amps which is nothing compared to car's cranking amps. However with good maintenance and water toping it'll last for long not to mention lithium batteries also have risk of getting fire or even BMS damage and it's not easy to replace from local shop next door.
@@ferdm9646 that's it exactly. For a long time I've suspected that the lithium fans haven't considered the cca ability of lead acids and that they can handle that kind of abuse if required and simply be recharged afterwards undamaged. Truth be told in an off grid scenario they never have to do it as it would fry most of the equipment. 😊
@@ourkilkennyhomestead2006 one more thing I wanna ask what type of batteries you're using , golf cart or leisure batteries ? I'm have two battery banks one of them are flooded tubular plate battery another one is AGM.

27kw of lead acid or gel batteries is only 13.5 kw of usable power, because the depth you are able to discharge them safely is 50%, 50 percent is half of what you actually have. What he has done is great, but I think he could do lithium now for the same money, and have 100% usable power,that will last almost 3 times as long as the batteries he has now,ie he would have to replace his batteries 3 times to get the life of the lithium. Did you save money,yes right now at start up,but not over time. Lithium will save you time,money and space,you just can't loose going lithium
@@dustydawson8977 would have preferred if you posted this as a direct comment instead of a reply. I stated clearly in the vid about the 50% discharge rate. Lithiums haven't come down to level price with lead acids here yet. They're still 3 times the cost roughly unfortunately. As for the longevity, ideally lead acids should be run like they are in a vehicle where they're kept in a constant state of charge. Approx 14.4v per 12v battery, once the lead acids aren't over discharged they're good for maybe 10yrs. Not saying one is better than the other. It's all how they're run. Thanks for checking out the vid 👍

repost ... There's more to it than just inverter reliability. A quality HF inverter can last a long time and has a fair amount of overrating capability too. Lots of the HF all-in-one units are neither of these things, even well known brand name units. The idle draw from most of these HF AIOs is quite bad, even the quality ones. It's not unusual to see them chewing 50+ watts with no load. 10 hours of no solar overnight, at least 500 watt hours out of the battery and another 500 watt hours that has to come from the solar the next day. Not insurmountable but has to be accounted for by way of a bigger battery and perhaps solar array too. Victron can get down to around 18W idle whilst maintaining a normal sine wave and even lower when permitting it to be slightly distorted (victron calls this a modified sine wave but it is absolutely not the stepped waveform most people think of) and in search mode, not really useful in a lot of situations, perhaps 10 watts. The power draw of Victron's solar chargers is low enough that it can be ignored for their units that do not have solar charging built in. Other quality LF inverters have similar performance figures. It's not just idle draw either, quality LF inverters often rival, even surpass, the efficiency of a lot of HF inverters. Of course there are terrible low frequency inverters that draw stupid levels of power with no load from elcheapo brands and have horrid efficiency too. There's another thing to consider with HF vs LF too, protection devices. LF inverters have no possibility of placing DC (or DC offset) on the output while HF has this issue, and I'm not talking about fault conditions but this certainly also applies there too. RCD protection on HF inverters should be a more expensive B type device. Swings and roundabouts basically. I'm not being critical of anyone's choice of equipment.
@@retrozmachine1189 ah another victron fan boy, now it makes sense. Listen fella, I've got nothing against victron. It's quality stuff but technology moves fast.

Such a false statement at 3:00. Home lithium batteries these days are all Lifepo4. These can be discharge 100% as I do mine on a regular basis. Lifepo4 are too cheap these days to be using lead acid anymore.
@@Firephosure the amount of charging cycles they can do reduces when they are repeatedly discharged below 80% so NO it's not a false statement. Also lifepo4 are still three times the price of lead acids so the only false statements are coming from you my friend.
