Re: [RE-wrenches] sol ark AGS question
I just replaced two Sunny Islands and one Sunny Boy that I did not install with a single Sol-Ark 15k today. The generator installer (not me) had already installed a custom but simple time delay relay. I didn't get into the logic of it, but from what I understand the generator already had a cool-down period when remote start signal is lost, but no warm up delay. Major deficiency? I think that is actually pretty accurate and Sol-Ark should fix it, but it isn't too hard to take care of it another way. I wonder if this has something with the distinction of accepting generator input on the grid input as well. You would not want a grid delay if it were a utility. Still, they should be able to build in that logic I would think.

Re: [RE-wrenches] sol ark AGS question
In an off-grid scenario I would suggest utilizing the grid connect timer as a Gen warm up. I typically set this qualification time to 30 or 60 seconds. Sol Ark fixed the problem with dropping the 2 wire start under full load, so if this is an issue for you, I would update the firmware.

Re: [RE-wrenches] Franklin Home Power
Jason, Wrenches I am familiar with Franklin and when I asked them about the battery they had all the answers but when I asked about the AC coupled inverter inside, mainly who made it is it field serviceable I got deer in the headlights and a few weeks later I asked them the same thing and again no answer. I would go with something that has been around some. You talked about Solark, I have had no issues with any of their inverters and my latest install was today connected to a fortress. Of course time will tell on anything we use, Maybe franklin has made it known what is inside but for me I will not use my customers as unknowing guinea pigs, I test products myself and see what survives.

Re: [RE-wrenches] Sunny Island/Fortress E-vault
William, Wrenches Yes I do and it does require some basic electronics to make it work correctly, you will need to remove the ttemp sender and make a resistor pack to simulate the 77 degree reading otherwise it will not charge properly, for the first one I used a breadboard to set the temp for what I wanted to see then build a more solid state shrink wrap resistor. Doing this will prevent undercharge by the SMA and your customer will be happy to see the full state of charge at the batteries.
