Re: [RE-wrenches] Sol-Ark with 800A Service

FYI Sol Ark sales engineer has suggested the following: “For the 15K, we've recommended AcuCT R Series - AcuCT-4161R-800:100mA | Accuenergy with 100mA output. On the inverter, you will need to adjust the CT ratio to 8000:1. Also note t

Re: [RE-wrenches] Sol-Ark with 800A Service

As an aside, I ran into this with a Fortress True 12kw. (As of several months ago) They have not tested parallel CTs, nor have they tested single CTs in any service above 200A. They would not approve my plan to parallel CTs on a parallel conductor, 400A service. Fortress does have an input for a 3

Re: [RE-wrenches] Sol-Ark with 800A Service

You should be able to parallel 6 CTs (3 per phase) as long as you get the phases and directions right. The question really comes down to whether the Sol-Ark can handle the current from 800A at the CT ratio (which I believe is 2000:1). For practical purposes, on an 800A service, particularly residen

Re: [RE-wrenches] Sol-Ark with 800A Service

Hi Jason, Sorry for not clarifying. This is a export limited scenario, so CTs would still be required. On Thu, Jul 18, 2024 at 6:51 AM Jason Szumlanski < ja...@floridasolardesigngroup.com> wrote: > This may or may not be helpful, but are you sure you need the CTs? They > are not always require

Re: [RE-wrenches] Sol-Ark with 800A Service

This may or may not be helpful, but are you sure you need the CTs? They are not always required. You would need them for power export limiting or grid peak shaving, but for straight grid-tied with or without battery backup, you don't need them. Jason Szumlanski Florida Solar Design Group On We

Re: [RE-wrenches] Sol-Ark with 800A Service

Hi Chris, I’ve asked them if they are compatible with rope CTs and they aren’t…. Please share the solution you arrive at, as I know I’ll need to repeat it soon. David ___ List sponsored by Redwood Alliance Pay optional member dues here: http://re-wre

[RE-wrenches] Sol-Ark with 800A Service

Hey there wrenchers, I am working on a larger project with 6 Sol-Ark 15K units and an 800A service. The main service conductors are 3 parallel runs of 400 kcmil. I am wondering how to CT these conductors from the master inverter. Sol Ark tech support has not been very helpful so far. I have the in
