Re: [RE-wrenches] Automatic load control
I use a Morningstar relay driver and 48 VDC relays to drop loads as the battery voltage drops. It works fine, and avoids the necessity of complex electronics.

Re: [RE-wrenches] Automatic load control
We have two Sol-Ark / Fortress deployments just finished/in progress and one uses seven Lumin panels for load shedding and the other has SPANs. In retrospect the Lumin project should have used SPAN since it was a new construction project and the Lumin is more of a retrofit product in my opinion. We have been pairing Lumin panels with Tesla Powerwalls for at least five years as a way of using a single PW to provide whole home backup and it's a very solid product with excellent support. I think we're going to see more and more standard electrical panels being built as "smart" panels that will include load shedding capabilities as demand management becomes more and more of a smart financial decision with rising energy costs. But for now it's still niche products like these. - Sam ___ List sponsored by Redwood Alliance Pay optional member dues here: http://re-wrenches.org List Address: RE-wrenches@lists.re-wrenches.org Change listserver email address & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org There are two list archives for searching.

Re: [RE-wrenches] Automatic load control
Aloha Howie, The Lumin Smart Panel has worked well for us. https://www.luminsmart.com/ Software is simple and tech support was on point. The app works well also. Bonus...you can remotely monitor power consumption on each controlled load. Two minor hang ups: 1. Having to run a separate "grid sense" circuit. This circuit has to be pulled from a location that is on the grid side of the Sol-Ark. This can be in a pain when the load you wanna dump is on sub panel clear across the property from the inverter. I am sure this the case with all these load shedding type devices. 2. You have to do a training to install them. It was a short webinar. Super easy.

Re: [RE-wrenches] Automatic load control
Howie: Segregated load distribution. Simple, automatic. I don’t get why they put 200 amp pass-through on an inverter that can only produce 62.5 amps.

Re: [RE-wrenches] Automatic load control
SPAN Panel, or you can try Generac 7006 automatic load shed device (100A) https://apelectric.com/generac-7006-smart-management-module/ Or G7000 (50Amp) I’ve heard they work with other inverters, not just GENERAC only, but of course you’d have no warranty when mixing brands.

[RE-wrenches] Automatic load control
Hi all, I am trying to figure out best options to control loads in a Sol-Ark15k battery backup residential system. It's been quite a few years since I've set up an automatic load control, and never with a Sol-Ark. The Sol-Ark will output to the main breaker panel, so no separate "backed up" panel - all house loads will likely be on the Sol-Ark's load side. What do folks like to use in this type of circumstance to automatically shed loads when the grid is down, either sequentially as the battery bank drops down or more simply triggered by loss of grid? Are they pieces of equipment that work specifically with the Sol-Ark? I'd also be open to considering Fortress's Envy, if there is an option that would work well specifically with it.
