No worries, yes I have been meaning to do an update. We are just coming out of winter and are now going into summer. There hasn't really been anything to report because they have been doing their job fantastically. I will however be packing up my setup and putting it into storage as I will be...

I'll let you know what that happens also! Also thanks for the confimation that I'm onto something. How do you know when your over the target? You take the most flack!

Here is another old Edison manual from 1914 https://web.archive.org/web/20120704014908/http://ironedison.com/images/products/Iron%20Edison/Edison%20Manual%20of%20Storage%20Battery%20Practice%20%28c%29%201914_.pdf

Thank you!! See what I did there? We cant have too many going off plantation now can we? Must keep them in the company store! Can't allow them to be free! Couple sets of panels + spare pot ash + deionized water + NIFE cells = lifetime Free energy device!! We cant have that now can we!! How does...

ok, there are a few points here that are simply not true... 1/ Yes these batteries are expensive compared to most so I agree, longevity costs money 2/ When the sun disappears for a few months then this will surly be a massive issue! I'll let you know when that happens. 3/ Its quite...

Its probably worse than that, lets remove 1000kwh (direct solar to load) so 1084/1265= 85% <-- yeah thats about right, roughly the same as lead acid!

Their no worse than Lead Acid, however if you decide to overcharge them to gain 30% capacity over the rating (as the old Edison manual says you can do), your efficiency will drop through the floor!! But if your on solar and its a sunny winters day and a storms a coming, you may elect to do that...

This year for the total system... Source 2265.84kWh, Load 2084.09kWh Probably half of that being direct solar to load, with the other half being via the batteries. But honestly, who cares? The sun shines regardless and panels are cheap!

Spring Update Well its spring time here now, and things are warming up, it’s amazing the difference between now and the depths of winter as to the amount of usable sun I'm receiving. Right now, I'm getting good sun from 8:30am through to 5:30pm or 9 hours where as I was getting around 6 in the...

Yeah I wish Inverters were as flexible as charge controllers are, but the cost of doing that is most likely quite prohibitive and its a limitation of the FET's used.

Edison Batteries are also called Nickel Iron or NI-FE. Checkout my thread.... https://diysolarforum.com/threads/ni-fe-1000ah-12v-with-5kw-of-panels-running-4kw-reverse-cycle-ac-for-heating-house.2490/ I go into great detail my setup, I have tons of data to backup my experience also. And I...

Yes 12V has been a little challenging, I'm running 70mm2 between the batteries and the fuses and 35mm2 between both Charge Controllers and Inverter (all separately) to the fuses. But as I go up in voltage I will keep my wire sizes which will also help with Voltage drop. Doing it this way...

Thanks great news, glad to hear it. I'm going to 24V first, but thanks.

Yeah no worries, well good luck!!
