Re: [RE-wrenches] Dual battery bank switch for 48 VDC system

Hi GregHow about this midnite box midnitesolar.comPersonally what I don’t like about single switch A or B is there is an off time. With the midnite box, you switch both on, and turn the off the one you want. That way there is never an off time. Just a thought. JayOn Jun 15, 2024, at 11:19 AM, greg

Re: [RE-wrenches] Two Outback Radian 8048 fails in same week..what is likely wrong in 7+ year inverters?

Call Zonna energy. It’s most likely 1 of the control boards. And probably not the power modules. Not all that uncommon especially for the non A versions. Jay > On Jun 9, 2024, at 4:50 PM, Scot Arey via RE-wrenches > wrote: > >  > Longtime Outback user but since the experience of this gr

Hi Scot What a fascinating issue. I can’t help as to the structural concerns but I like the deck mounts idea to make sure you don’t have any issues. Jay > On May 29, 2024, at 4:17 PM, Scot Arey via RE-wrenches > wrote: > >  > With all our Texas hail storms, we now have roof solar systems

[RE-wrenches] Discover rack mount battery connectors

Hi all I’ve noticed that many batteries are now using a different type of battery connector. Almost like a kind of MC4. It has a positive locking mechanism. Discover, EG4, and others. I’m wondering if anyone knows if they are universal or specific to each brand? And is there a name for this t

Re: [RE-wrenches] Discover AES exposion

That is fantastic service!  And it also confirms  that LFP batteries are actually capable of the same explosive energy ( even more actually) as NMC contrary to the claims made by many that it’s impossible. While I’m using LFP batteries in most systems, it does scare me much more than Lead. JayOn Ma

Re: [RE-wrenches] Water system with Grundfos SQFlex

HI Brad, Is this off/on grid? And are the two wells near each other or they just join up at the tank and float switch? If you’ve got the power then I’d install just a standard AC centrifugal pump. Sure uses more power but lasts forever. And is maybe $500 vs $2500 And you’ve said minimal water

And of course using a torch to soften the tubing just enough so that the barb fitting can insert and then grab into the plastic with the clamps. For 1” its not needed but helpful. For 1.25”- 2” its needed, or at least I’ve never been able to get a solid connection without heat. Jay > On May

Re: [RE-wrenches] Water system with Grundfos SQFlex

Hi Brad With 2 check valves leaking I’d look for a broken pipe or a corroded fitting. If there is anyway to isolate between the 2 check valves then you could measure the pressure drop on both sides which should point to the direction of the leak. Jay > On May 25, 2024, at 7:41 PM, Bradley B
