What is EG4's GridBOSS? (complex, yet simple!) | Overview with Brayden

[@michiganengineer8621]

It sounds like you would still need an "anti-islanding" switch to disconnect from the grid if/when the grid fails. I like the idea of how this brings ALMOST all of the external connections between the grid, your hybrid inverter(s) and your main breaker panel together into one box.

[@eg4electronics]

The GridBOSS handles all anti-islanding needs, complete with the UL certifications necessary. It has those functions built in!

[@michiganengineer8621]

@@eg4electronics I went to the site after I commented and read through the specs and saw that. Thank you for the reply!

[@DiySolarHelpDesk]

I'm missing something, and I don't see it in the manual either. The Grid Boss Hybrid ports are for the "GRID" input to the Hybrid inverters. Where do the EPS outputs from the Hybrid Inverters connect? Without those, there is no backup. The diagrams all show just 1 port being used for the Hybrid inverter and that doesn't make sense if the grid fails. That's when the EPS port takes over.

[@eg4electronics]

Tight communication with our EG4 hybrid inverters allows the GridBOSS to control whether that port stays operational or not. This is important as the grid disconnection is now located within the GridBOSS (when using its architecture). Using the grid port on the inverters allows for unique future features to be added to the EG4 ecosystem!

[@DiySolarHelpDesk]

@@eg4electronics My only complaint with EG4 inverters is I wish they were convection-cooled like Hoymiles inverters. They run totally silent.

[@collinlindgren3591]

​@eg4electronics I thought that's what the idea was here, but I'd like to see this wiring diagram. The manuals for both Boss products specificity exclude a wiring diagram so it's not clear. Also, page 33 describes a No Sell Back scenario in which the non-backup loads recieve power from the inverters during an outage. How can this be done with 1 relay and still be safe for the grid linemen?

[@eg4electronics]

The non-backup loads will not receive power when the grid/utility is offline, that's what the relay is for. The situation it is describing is that when grid is present, the inverters can still offset the power usage on non-backup loads, but won't sell excess power back to the grid.

[@scottsattler4973]

bought flexboss and grid box after this video...

[@MyGoogleYoutube]

If you already have a 200A breaker right after your meter do you still need to add a 200A breaker in the Gridboss?

[@eekedout]

Their wiring diagram says no

[@MyGoogleYoutube]

@eekedout Agreed.

[@scottbalak7123]

Very informative and interesting in how grid tie inverters can be integrated through the smart port as I currently have a 10kw Growatt. I'm in MA and we have 1:1 net metering. I have two EV chargers (48a + 80a) and I'm curious if the smart ports can load shed based on current draw? For example, can I set up logic in the GridBoss to open the SP1 relay if the panel draw is >50amp? I was also wondering if the GridBoss can control maximum grid export rate? I need to stay under 25kw, but a Flexboss 21 (16kw) + 10kw Growatt is just 1kw over my limit. If I need a 25kw cap would would you recommend? Limiting the inverter or can the GridBoss limit? Thanks!!

[@Upliftyourbrothers]

Cool! What are the benefits of this over a Schneider BCS?

[@eg4electronics]

Nearly all MIDs currently in use are proprietary with the hybrid inverters they can use (with pretty good reason being tight communication protocols, admittedly), so the using the GridBOSS allows you to take advantage of the full EG4 ecosystem in all the ways described in the video (and more!)

[@AndrewVanTil]

Can you use this with a service that is greater than 200A?

[@ericjansen9042]

Great break down

[@jamesgor13579]

Requiring copper wiring is a major limit. Many large connections are going to be aluminum SER. Especially if the inverter and batteries are not located near the service entrance.

[@andyfromtoystory7426]

You can use aluminum, but the thickness of the aluminum wire would be much thicker than copper and it wouldn’t fit into the connector. That’s the only reason they say copper, that’s a statement from their CEO. The inverter itself will work the same with aluminum if you can get it hooked up.

[@jamesmartin2339]

Does the flex boss and gridboss support the Ethernet adapter that the 18kpv support?

[@user-jm7jk6xu2r]

Regardless of connection, it appears that a meter pull is inevitable? Wish there was a way to connect without having to cut power to my entire house for half a day.

[@surfcow]

Well done, thank you.

[@benjaminsuddeth6448]

I want smart load for your offgrid inverters. To turn on non critical loads when batteries are charged and off when excess solar is limited before draining batteries.

[@eg4electronics]

Our 12000XP Off-Grid Inverter has a single smart load port with this feature integrated for this scenario. It can be used with either power shedding (where you activate it during excess generation) or load shedding (where you deactivate it when you drop below a certain storage threshold) which let it work dynamically.

[@Marlin-m9m]

Can you connect 110V portable generator to one of the smart ports just to supplement the solar/battery power available during grid outage?

[@eg4electronics]

You'd need to connect the gen to the batteries via a ChargeVerter for supplemental power. The generator you're describing is likely too underpowered to integrate into the GridBOSS.

[@claygone305]

This product looks great. Are you going to add support for grid export for batteries? Grid stabilization with utilities would make this a killer product.

[@Barc7580]

Is the grid boss a good option to connect back to an interlock breaker in the main panel plus connecting to a sub panel running grid up only devices such a a pool filter and pool heaters?

[@tombrownca]

Do you have a diagram for how one might connect GridBoss to a home? Like, show main meter and breaker box, show PV array, show the wiring connections in a diagram.

[@eg4electronics]

More in-depth information can be found in the manual located on the GridBOSS page here: eg4electronics.com/categories/inverters/eg4-gridboss/

[@bill2292]

Great looking new product, but I don't yet see pricing on the website. I really appreciate the explanation without the use of acronyms and buzzwords.

[@eg4electronics]

Thank you for the kind feedback! Pricing is available at our certified distributors listed on this page: eg4electronics.com/distributors/

[@frostyfroze7352]

Will this be service entrance rated in Canada? CSA or cUL

[@aday1637]

I like the innovation at EG4. However, this presentation is a bit dry as to what you are actually selling. I'd like to see a more practical presentation with real world hook ups to ascertain the usefulness to me. I currently have my grid incoming to a utility building then sub off of that to various other buildings such as my home, shop, barn, etc. I'd like to see if integration is feasable or possible and whether the unit is capable of providing me with any advantages. I do not have nor ever will have any of my solar components in or near my home as I don't trust any type battery for safety. Hopefully, you will provide us with more/better videos on the merits of this device and it's upcoming 'companion' device with the grid buss bar. Thanks

[@davefroman4700]

Just fyi? The vast majority of LFP battery fires? Are not the actual batteries. Its the BMS that is normally to blame for any issues with them. New equipment designed for indoor use has onboard extinguishers in the BMS area of the battery for precisely this reason.

[@davefroman4700]

Let me know when they come out with a simplified Off-Grid Boss with smart loads.

[@dalltex]

Can you add an off grid inverter like a 6000xp to one of the smart ports? I'm still learning

[@cell8290]

I also had the same question. I am not sure but I'd say no. Only because he keeps saying we can connect "hybrid inverters" and on the gridboss it says "hybrid inverters". Who knows, they might actually support off grid inverters like 6000xp too?

[@edaugsburger6486]

from what i am reading yes the 6000xp would be connected to one of the smart port

[@dongemus]

The official answer I've heard is "not at this time" but you were able to hook a 6000xp to the 18k via the generator port. Not sure why you couldn't do that here

[@dalltex]

@@cell8290 Thanks! I was thinking that the hybrid inverters connected to the hybrid port would work better but wasn't sure about the smart ports since he said it could connect to AC and DC coupling I believe. I need more knowledge but learning a little at a time.

[@Aubatron]

I remember signature solar saying it’s a stand alone system and will not communicate with other eg4 devices and is not really meant to be put in parallel with more panels like a lot of the other devices are. Don’t know if that answers your question.

[@dennissmith1469]

How many units would be needed for a full Electric home! To start with two 5 ton heat pumps, 220 volt double oven and 220volt stove top, 220 volt water heater, 220 volt well pump, I live in Florida and the whole house is Electric. Or can I speak to someone?

[@parkerwatts3334]

I would say 2-3 but other than the 5 ton heat pumps... the others are hard to say what they would draw without an amp rating, luckily the surge capacity is really good in these so unless you are running over capacity constantly.... I wouldnt see having much more of a need than 3... sure way to tell is to have a clamp reading each leg at your house and have everything cut on at the same time and see what your peak is...

[@christopherfoote3395]

One. This is not an inverter. The inverter is what determines that. Probably need one of the flexboss inverters with a few batteries.

[@dennissmith1469]

​@parkerwatts3334 i know a 15 kw Genarator can't not run my whole house! Actually, I can't really even start the one 5 ton heat pump! I've heard the ideal of hook in parallel extra inverters. But before spending i like to figure out how many it would take and break down of all the components i may need.

[@dennissmith1469]

​@@christopherfoote3395I know this is the load unit. But it's only handles up to 3 inverters. Batteries i already purchased. I've purchased 48 SOK 48 volt server rack batteries with the outside enclosure. Now I just need to pull the chains on how many inverters I need to run my whole home and how many of these Grid bosses must be use. Or I'm going with Victron

[@parkerwatts3334]

@@dennissmith1469 if you dont have a soft starter.. that is why you cant run your heatpump

[@andrewcoonradt]

@EG4 Electronics You do not need a Feeder Tap anymore, is that correct? You still show it in your diagram, believe that is a mistake.

[@idahoduckhunter]

Isn't the main breaker integrated into this also? Seems we go meter base straight into the grid boss. I guess it's still good to have a switch before the grid boss so you can hook it up and not die. My bad.

[@vinny143]

Is this better than 4 - 6000xp's

[@joshomary7977]

Its not an inverter

[@joshomary7977]

Maybe look at the FlexBoss21 or the new 12000XP

[@aday1637]

In my particular set up I found that the transfer switch in the 6000 model won't work for me as it requires I tap in prior to the main panel and after the meter. I don't want to break the seal on the meter to allow wiring in and was wondering if this unit could somehow alleviate that issue. I've hesitated with purchase of any EG4 equipment until I can obtain more information as to actual functions. This stuff shouldn't be a mystery with fancy terms to describe it's use. I really need a more comprehensive video with real world use and thorough description of its advantages. Barring that I doubt I'll ever purchase one of these products. I own a host of solar products for back up to grid but have come to the conclusion that installation of the solar will only occur after the grid goes down. Not my ideal set up but it is more understandable than dealing with unknown characteristics and features of one of these automated devices.

[@vinny143]

@joshomary7977 i have 4 -6000xp's and one is hooked to grid breaker to charge when 30% SOC is reached,, then it charges to 60% SOC. 10k of solar
