I just made quote for a person with 600 amps main and a 200 amp essential load panel.True that. I can believe EV chargers will increase the loads at a lot of residences, but even with EV chargers, a full 400A load is well beyond what most residences will ever experience.
With my EV charging (32a) 3 air conditioners running and some other appliances, my loads just barely hits 12KW. 400a is a boat load of power.True that. I can believe EV chargers will increase the loads at a lot of residences, but even with EV chargers, a full 400A load is well beyond what most residences will ever experience.
Still doubtful.I just made quote for a person with 600 amps main and a 200 amp essential load panel.
I wouldn't want to make a bet that with their new EV they might be able to pull 400 amps
I have no doubt there are people that will need 400A service (or at least have it), but it will be the exception. not the rule. 200A service seems to be the norm for most middle-income homes.I just made quote for a person with 600 amps main and a 200 amp essential load panel.

No, 60Hz only.
You have 50Hz split-phase service?
Looks like the datasheet on SS' site shows it can do 50hz. In the eg4 manual it says it autodetects but gives a freq range starting at 55hz so the datasheet and manual are a bit at odds with each other. I suspect the frequency is controlled by software so hopefully SS can confirm the frequency ( @SignatureSolarJames ) and/or provide a firmware update.This is a pity. I hope that this will be a feature one day. There are some markets that use split phase and 50hz in Latin American and the Caribbean, for example Jamaica where Sol-Ark has been doing very well.
Can someone from EG4 confirm that it is 60Hz only? I see the Fortress version can do nominal 50hz/60hz...
The answer is YES. The frequency will be automatically adjusted to fit the grid frequency. No problem using it in Latin America at all. besides, in Jamaica, we set up a sole distributor there more than a year ago.This is a pity. I hope that this will be a feature one day.

I've heard this name Adam De lay in a couple of threads recently, who is he, and why is his opinion important?Will's initial review was great. Would also love to see Adam De Lay create a review series on this. Adam is like an inverter scientist going really deep into testing and such.
@Adam De Lay has done some great deep dives into the EG4 6500 inverters on YouTube.I've heard this name Adam De lay in a couple of threads recently, who is he, and why is his opinion important?
It’s not.I've heard this name Adam De lay in a couple of threads recently, who is he, and why is his opinion important?
OK, thanks for sharing that Henderson. it seems more complicated than it could be. we are in talks with them regarding the application in that video. but now, you may please neglect that, and refer to what I replied above. Thxgo to 1:11:38. Again, this is the Fortress Envy which appears to be spec on spec to the EG4 18K PV.
Not entirely true. Look at my signature. You can use 3 EG4-6500 effectively. I was going to do split phase x 2 (4 eg4's required) but after running 2 of them, not necessary to do split phase x2. Even though I have 4 Eg4 inverters, #3 has become a 100amp battery charger (low sun or faster charging when desired). Inverter#4 has become a spare if necessary. 2 EG4's in split phase runs my entire house and has a ton of spare power. Most of the time power usage is less than 20%. Running freeze dryer and 3.5T A/C today with power draw at only 40% max.You are correct, I hadn't realized this point. Thx
He has a methodical approach to a lot of the technical aspects of inverters. Especially the software and it’s functionality. And that can be extremely helpful to people. That’s likely why you’ve heard his name come up.I've heard this name Adam De lay in a couple of threads recently, who is he, and why is his opinion important?
I took some pictures of the internals of my LP12k.The new EG4-18k looks very promising, but we need more testing to see if it can deliver.
We need to see if it has similar problems as the SolArk in certain applications:
5. Is the MID relay rated for 200 A?
Is the relay the top-of-the-line 200A Gruner relay as in a Tesla Powerwall MID panel or as in a FranklinWH aGate or it is a chinese knock-off?
We're currently doing a multitude of edge-case testing for some of these scenarios that people are looking for. We have some videos in the works as well to demonstrate the results of our testing, so stay tuned for that!The new EG4-18k looks very promising, but we need more testing to see if it can deliver.
We need to see if it has similar problems as the SolArk in certain applications:
1. AC coupling is disabled for now in off-grid mode ( according to the manual)
this effectively means it is not working!
2. Will AC coupling work with stacked units in off-grid or backup mode?
3. How about AC coupling with legacy inverters, that do not support FW, VW or VV, is there a PV disconnect relay for AC coupled inverters in off-grid mode and for compliance with EPO?
4. Need load imbalance testing at full imbalance, SolArk has problems with max imbalance.
( see Dean Abney's video at: SolArk Testing)
5. Is the MID relay rated for 200 A?
Is the relay the top-of-the-line 200A Gruner relay as in a Tesla Powerwall MID panel or as in a FranklinWH aGate or it is a chinese knock-off?
The relays built into the 18kPV is the Churod Char-112A200. They have a make/break of 50A, but can carry 200A and have a max break of 220A.Braydan, please give us the 200A MID full relay specs and manufacturer datasheet link - break and make ratings - so we can verify.
I know Eddie answered, but yes it does support 50hz. It will autodetect based on grid frequency. The spec sheet will be modified to clear up confusion!This is a pity. I hope that this will be a feature one day. There are some markets that use split phase and 50hz in Latin American and the Caribbean, for example Jamaica where Sol-Ark has been doing very well.

May I suggest you spend a little more time on the PDF document linked to. It can handle 830 volts at a maximum 200 amp and is indeed rated to 220 amps. Would I trust it to do this more than half a dozen times, absolutely not. And there looks like there's quite a few of them in the inverter so I'm assuming there's one per phase.The 112A200 relay is a 1-pole 200A 12V relay, with a 50A make/break rating there is no 220A max break! Where do you get the 220A max break rating from? If you break/make 200A with this relay it won't last very long! And it looks like the grid and backup terminals are not rated for 200A either! Additionally, you need 2 relays for the split-phase MID disconnect. And there is no feedback contact to verify that the relay is still operational and not stuck!
