Re: [RE-wrenches] Tesla Powerwall

Mr Hill The PW is AC coupled so any inverter but the newer the better with Freq shift capable may take programming to work best. Jerry On Mon, Feb 1, 2021, 10:03 AM Jonathan Hill wrote: > So it can be used with a Sunnyboy, correct? Have you ever installed one? > > Jon Hill > Solar design enginee

Re: [RE-wrenches] Load imbalance issues with SolArk?

I have concerns as well, because I too have been considering the SolArk for upcoming larger designs.  I regularly expect the builders to test the system and expose any problems before the owners move in.  It should be able to run any properly operating 120 v equipment there is.  Having said tha

Re: [RE-wrenches] Load imbalance issues with SolArk?

Nick, Larry has it correct, the 4kW autotransformer (PSX 240) will use both of the 120-volt legs of the inverter. It has two winding each able to handle one leg to neutral, but able to transfer power from one leg to the other. You can have 8000 Watts on either leg, one at a time, continuously,

Re: [RE-wrenches] Load imbalance issues with SolArk?

Hi Larry I’m not so sure about that. The X-240 doesn’t work with the Radian or FXR versions. IE it won’t balance the loads so that the inverter sees a balance on L1/L2. It did do this for the older FX versions. Jay > On Feb 3, 2021, at 2:10 PM, la...@starlightsolar.com wrote: > > Amos,

Re: [RE-wrenches] Load imbalance issues with SolArk?

Hi Nick, The 1400w difference is in terms of a DC load on an AC output, which is common when using variable speed appliances that use internal diodes that modify the sine wave. This does not apply to true AC loads where the Sol-Ark can do 4800w continuous at 120V. Dustin Douglas Engineerin

Re: [RE-wrenches] Load imbalance issues with SolArk?

You can have 120V circuits that would never need line balancing and 240V loads on the main panel. Then put any 120V circuits that may need line balancing on the PSX sub panel. Larry On Feb 3, 2021, at 2:21 PM, Amos Post wrote: Thanks Larry, This would be a 240V to 120V step down configura

Re: [RE-wrenches] Load imbalance issues with SolArk?

Hi Nick, We have about 16 SolArk's installed and have a single 12 kW that has that "bus imbalance" error every once in a while. It seems to be a specific appliance (electric mixer) that it does it with, and only occasionally. I spoke with SolArk about it and they have a small "plug in" that does

[RE-wrenches] Load imbalance issues with SolArk?

Good morning Wrenches, I’ve strongly been considering using the SolArk 12K unit for awhile but have heard from a few folks that there can be somewhat frequent issues with the inverter shutting down from line to line imbalance. As little as 1400 watts? I could see where these instances would be

Re: [RE-wrenches] Load imbalance issues with SolArk?

Thanks Larry, This would be a 240V to 120V step down configuration correct? So the sub panel would be 120V only? Best, Amos Amos Post Integrity Energy W 802.763.7023 C 802.291.2188 ienergyVT.com Facebook

Re: [RE-wrenches] Load imbalance issues with SolArk?

Never had this on a Radian or XW BTW. It would be a deal breaker for me to lose power EVER from this! I hope it is wrong! Seem like nice folks at solark. New construction is always a risk also as contractors have the junkiest power tools. There are people who think they can arc weld off an offg

Re: [RE-wrenches] Load imbalance issues with SolArk?

We have had this issue with a recent installation. It’s a new off-grid house build, and so not many loads to speak of yet, except mainly power tools. The Solark 12K will not start any of: portable air compressor, table saw, and sometimes struggles with a miter saw, which are each 16amps or les

Re: [RE-wrenches] Load imbalance issues with SolArk?

If it turns out to be true, could you simply add the Outback PSX-240 to balance the loads? Larry Crutcher Starlight Solar Power Systems On Feb 3, 2021, at 10:52 AM, Nick A Lucchese wrote: Good morning Wrenches, I’ve strongly been considering using the SolArk 12K unit for awhile but have h
