Does anyone know if Lorentz pumps still exist in the US. Someone is looking for a PS200 control box. It seems to be intermittent Thx Jay ___ List sponsored by Redwood Alliance Pay optional member dues here: http://re-wrenches.org List Address:

Re: [RE-wrenches] Recommendation on DC Breaker

I’d use an IMO disconnect as you don’t have any current limitations. I think sometimes things get lost in translation. Jay > On Jan 18, 2024, at 8:43 AM, Jason Szumlanski via RE-wrenches > wrote: > >  > I am installing an EG4 off-grid 3k inverter for the first time, and the > manual

[RE-wrenches] sol ark 15kw

HI All, I have some sol ark 15 questions, and I’m sure someone out there has the answer as I can’t seem to find it in their literature How much can it output AC with solar: offgrid and ongrid in sell back mode. What I read was 15kw, but I can’t figure out if thats both on/off grid or not?

Re: [RE-wrenches] Odd battery charging behavior with Outback inverters

There is or was a setting in the mate 3/s that the rebulk volts has a trigger. If the voltage doesn’t get below it it won’t charge (absorb) properly. Fix is to set the rebulk up higher than the charge voltsI don’t know if that’s your issue or not but I have fixed this  on systems. JayOn Jan 12,

Re: [RE-wrenches] Recommendations for A/B battery switch

HI Ron, I prefer to use two ON/OFF switches rather than A/B. That way you can always have power to the loads if you want. I can’t say they are the best but the Perko 9703 seems high quality and has been around for years. Its just a single on/off rated at 450 amps continuous and UL marine.

Re: [RE-wrenches] SMA TL-22 insulation resistance error

Re: [RE-wrenches] 48 V DC temp sensing relay

Hi Drake Try this one. I get a lot of equipment from supply house. Since you need on with temp rise it’s an AC type. This one will do 8 amps at 120v so a small amp dc fan won’t hurt the relay. Jay

Re: [RE-wrenches] Mate 3s with legacy FX inverters

Agreed to all said. Numerous systems with mate 3/3s and every inverter and stacking is all fine. New hub 10:3 required. MX CC don’t appear on the mate 3/s. Few of my systems are on optics so can’t comment on that. JayOn Dec 12, 2023, at 1:15 PM, Roland Shackelford via RE-wrenches wrote:We have

I’m wondering if anyone has recommendations for an inexpensive hydraulic KO tool. I have a project where I need to punch some 4” holes in gutter. I can’t get a jig saw or anything in there and a 4” hole saw bit is crazy expensive. There are many inexpensive hydraulic tools out there that

Maybe someone else knows differently but it was explained to me that the fortress batteries have a relay that disconnects the battery if the voltage gets to high or low. There isn’t any electronic  device to change battery impedance besides what the actual cells are doing. JayOn Nov 12, 2023, at

Re: [RE-wrenches] Cable sizing for high current modules? NEC interpretation/guidance?

I’ve wondered what other variables are at work given that mostly these connectors work as they should. I’d like to see them come with plugs covering the openings. This would keep dirt, salt air, moisture, etc  out until they are connected. As to if there were lots of failures with SW modules then
