Re: [RE-wrenches] Water Pumping 24/7

Wrenches: I found some on-line pump HP calculators, such as this one. Plugging in 1 gpm of water pumped to 300 feet elevation results in 0.1 HP, not 5. I have no idea how Daryl arrived at 5 HP. Plugging in the 10 gpm we want, the HP requ

Re: [RE-wrenches] Ideas and racking systems for "stowing" ground mount PV array during snowy winter?

Blake, You might try David Katz's single row system on 4" posts, it would tilt to vertical and only be one mod high in portrait. He does not have engineering on it, but it is very beefy and would have no issues as long as you tilted it up in winter. I am very interested in more info on what you ha

Re: [RE-wrenches] Water Pumping 24/7

Thank you William, I did it from memory, which I should not trust at 85 it is screwy I should have gone back to 'first principles' instead of trusting the memory of an old job. Thank you On Fri, Apr 1, 2022 at 9:23 AM William Miller via RE-wrenches < re-wrenches@lists.re-wrenches.org> wrote: > W

[RE-wrenches] Sol-Ark grid tie question

If you set up the inverter in a straight grid tie mode, does it still pass power through to the load terminals when on grid? I ask this, because a client wants us to connect it with a backup load panel but no battery right now. He wants to add the battery later. My other thought is to install a b

Re: [RE-wrenches] Sol-Ark grid tie question

Jason, this will work just fine. I’ve not fully embraced a transition to their products for my clients yet but had one recently where the customer insisted on this for their project and I was in the exact scenario while we waited for the battery to arrive. No external bypass required for this re

Re: [RE-wrenches] Sol-Ark grid tie question

Fantastic. Thanks! As a follow up, he's considering connecting a battery bank with an Anderson connector. This is not the golf cart scenario I mentioned in another thread, but he wants to be able to wheel away his battery into storage. Don't ask me why... I can't figure it out myself. Do you see a

Re: [RE-wrenches] Sol-Ark grid tie question

Hi Jason, If he removes the battery bank, then the battery mode setting would need to be changed to “no battery”. Luckily, very easy setting to access either in front of the unit or remotely. Best, Chris On Fri, Apr 1, 2022 at 2:52 PM Jason Szumlanski via RE-wrenches < re-wrenches@lists.re-wre

Re: [RE-wrenches] Sol-Ark grid tie question

Jason The programming is different with a battery vs no battery so if he is removing the battery this may create an issue, I have not tried myself to disconnect a battery once in place Jerry On Fri, Apr 1, 2022 at 11:52 AM Jason Szumlanski via RE-wrenches < re-wrenches@lists.re-wrenches.org> wrote

Hello, Blake Gleason & All the Mechanix~ Travis Jordan astutely suggested "David Katz's single row system on 4" posts, it would tilt to vertical and only be one mod high in portrait." Mick here: If the site would accommodate something as wide & low as what Travis described, you might ask Array Te

Re: [RE-wrenches] Sol-Ark grid tie question

It absolutely does. It works well in that scenario as well. No battery? No problem until the client decides to purchase and install some storage! Pretty versatile compared to a truly "Battery Based Inverter" like Schneider/Outback. . On Fri, Apr 1, 2022, 9:29 AM Jason Szumlanski via RE-wrenches <
