[RE-wrenches] Admin posting: Sol-Ark on list

Hi gang. If you have any questions or comments, please send them to me off-list. I've had several of you suggest to me off-list that Sol-Ark should have a manufacturer's representative on the list. I agree. On 8/28, one of their employees requested to be added. I responded with my standard spie

Re: [RE-wrenches] Microgrid... Outback or SMA or other?

Hi folks--We've just finished our first dual 12kW Sol-Ark install (replacing a Fronius 10kW from 10 years ago) and I have a few comments on  the recent questions. First, Sol-Ark started with a frustrating manual, but they are improving. To address Dave's question, the on-line manual for the 8k i

Re: [RE-wrenches] Microgrid... Outback or SMA or other?

Related question, Jeff... With the Sol-Ark, I an off-grid situation can you set it up to always use inveters to power loads. In other words, when the generator kicks in, only use the generator to charge batteries and do not bypass inveters to power loads directly from the generator. This is a requ

Re: [RE-wrenches] Microgrid... Outback or SMA or other?

I am confused by the 2 different Sol Ark systems. The large one looks like it has a DC disco/breaker and a solar disco. The smaller solark looks like it has a DC breaker only. Any guidance on what else is needed to make these useable please? Dave Angelini Offgrid Solar "we go where powerline

Re: [RE-wrenches] Microgrid... Outback or SMA or other?

I'm loving my first install of Sol Arks - One downside of Sol-Ark (and I can't find many!) is that the GEN terminal can only handle 1 of the following 3: Generator, AC Coupling, or Smart Load.  So if you want both a generator and AC coupling you have to either do a separate transfer switch for

Re: [RE-wrenches] Microgrid... Outback or SMA or other?

Yea I'm wondering the easiest way to get a 125 AMP Midnite Inverter Bypass assembly in a simple box for 2 Sol-Arks.  Midnite would be the perfect candidate for a simple support box (e-panel style) for Stacked Sol-Arks. Any ideas? Thanks, Jeff Dave Angelini Offgrid Solar wrote on 9/10/20 9:3

Hi Wrenches, Does anyone have a good 10 year service warranty clause to draw from in the sgip equity resilience program application? Not sure how to find the best verbage for this. It is referenced on page 61 of the 2020 sgip handbook. Thanks! Vic Guillot Vic Guillot Sol Sierra, Inc. 209.795.3554

Re: [RE-wrenches] Microgrid... Outback or SMA or other?

In an all in one, the good parts are balanced, sometimes, by a small failure making the all in one useless. Only a complete spare will save the day, or night...Also wonder about real world surge capacity on 1 hp pumps and big air compressors. I am glad to hear that they will be making this in T

Re: [RE-wrenches] Microgrid... Outback or SMA or other?

We've had great luck using the Tigo (and SMA) optimizers with SolArk to conform to NEC2017 and CEC2018. > There is a huge distinction in a hybrid inverter that integrates MPPT > charge control. Eliminating all of the extraneous hardware and circuit > protection associated with charge controllers

Re: [RE-wrenches] Microgrid... Outback or SMA or other?

There is a huge distinction in a hybrid inverter that integrates MPPT charge control. Eliminating all of the extraneous hardware and circuit protection associated with charge controllers is very appealing. The 500V input limit is also a game-changer in terms of wire size. I'm very interested in thi

Re: [RE-wrenches] Microgrid... Outback or SMA or other?

Hey Bill, They're still small enough that, at least so far, there is no hold music! And we combine ac outputs with an "ac combiner panel" simply a single phase or three phase panel, with each inverter feeding a breaker in that panel and ensuring that we use either a main breaker that can be back

Re: [RE-wrenches] Microgrid... Outback or SMA or other?

The largest we've done is a 4 stack of 8k Radians and a 6 stack of Sunny Islands with the Mutlicluster box. They both have worked fine and there are advantages to each approach. An advantage to a multicluster approach is that you can have smaller and segmented battery banks that don't require cus
