The EG4 GridBOSS beats every Microgrid Interconnect Device (MID) / power gateway on the market in terms of capabilities and ratings. The GridBOSS simplifies the design and operation of complex solar installations, reducing hardware costs and installation time. Featuring four intelligent ports for AC coupling or smart load management up to 125 Amps, it consolidates multiple electrical components into a single device with a 200A service entrance rating.
The GridBOSS serves as a centralized connection point for utility power, up to three 90A hybrid inverters, four programmable smart/AC-couple ports, and a generator (up to 125 Amps). It is rated for 200 Amps for both backed-up and non-backed-up loads, ensuring seamless operation under high load conditions and continuous power to essential loads during grid outages.
When paired with the FlexBOSS21, the GridBOSS significantly reduces installation expenses by eliminating extra components and installation time, making it an efficient, cost-effective solution for whole or partial home backup and microgrid setups.

I almost NEVER leave a 5 star review. They are reserved in my world for places that do something EXCEPTIONAL. Kyle A. And the crew at Cabin Depot are a group of those exceptional people. They patiently worked with us as we developed our off grid setup and provided not only fair prices, but wonderful follow-up with my installation and operational questions as our system came together. Thank you and we look forward to a continued relationship.
I purchased a drolet myriad III wood stove from cabin depot. Customer service was great, delivery was fast and they replied to all of my questions very quickly. When I received the wood stove I unboxed it while the driver was here (as suggested by the company). Everything was perfect and the driver from midland transportation was very accommodating.
A+ thank you very much!
I’ve taught customer service to many organizations in my professional career. I’m now long retired and still find excellent customer service difficult to come by!
The Cabin Depot, and especially Kyle Aubin, are exceptional examples of customer support and service!! My only regret was not reaching out sooner!
I would have saved myself significant time, lessened aggravation, and a happier installation of my EG46000XP and generator backup.
Lyle’s patience and response time, his pleasantness and professionalism, will contribute significantly to me looking first to them for future sales and service!
Recently added a EG4 LL battery to my existing system.
Cabin Depot was great to deal with, shipping was around a week., which is pretty good considering it was shipped across Canada.
Only delayed by 1 day but that was a UPS thing.
This battery was added to 3 existing EG4 Lifepower batteries.
Everything worked no issues at all., only thing was the communication ports are in different locations and the supplied cables are too short to reach,
No big deal.
All in all very happy and would order again
Propane stove came on time in perfect condition, super easy install, helpful customer service, very competitive price!! Just a good company. We will be buying more off grid supplies from this fantastic group of professionals!!
I was so impressed last year when I called from Alberta - searching for the right equipment (hot water on demand and propane heater… and I have to say I am impressed again - today was just a special order thermocouple to have as a spare - the service you provided for a 35 dollar part was above and beyond.
