HI All, I wanted to revisit this thread for one reason. If you turn off the inverter at the remote on/off with the AUX relay, then starting the generator won’t have any impact as the inverter is off. So someone will have to go and reset the AUX relay. Vs If you do a relay on the AC output, w

[RE-wrenches] Outback lithium LVD

I apologize in advance if this is a duplicate. I was contemplating the discussion about how to deal with an inverter that doesnt have the correct LBCO for a lithium LVD voltage. A suggested option for OB was to install a relay triggered by the AUX and controlling the inverter remote on/off sw

back on the next day.  This is my concern on Solark installs, I just noticed that the inverter won't pass through PV, if it hits its LVD set point.  On 7/20/2023 3:04 PM, jay via RE-wrenches wrote: HI All, I wanted to re

Re: [RE-wrenches] Inverter output fluctuations

Given that it worked fine for years it would appear that the XW+ has an issue. I don’t see how the SE could cause this. Is it still under warranty? What does Schneider say about the issue. JayOn Jul 22, 2023, at 10:33 PM, Howie Michaelson via RE-wrenches wrote:Michael, that is my last ditch choic

[RE-wrenches] Solar edge question

Hi all For all you SE experts. I got contacted from someone who has an offgrid system of a SE 7600A and battery. Works fine. They want to connect to grid power, which is right at the street because they want an EV. My question is, what do they need to make this a normal sell back and batte

[RE-wrenches] sol ark AGS question

Hi All, I have a client with a sol ark and it doesn’t have warm up or cool down, kind of amazing companies are going backwards in their tech. Has anyone come up with external fix for this? I am guessing the internal relay on the sol ark switches closed when it sees the correct volts/hz and o

Re: [RE-wrenches] GT w/ BB

If 40kw is the peak and then there are new added loads, what 50-60kw?  If it was me I’d be designing the inverters to handle the 50/60 kw with future expansion capabilities beyond that. Then how much kWh of storage are you going to need or maybe are planning for?At some point maybe looking at a lar
