EG4 Upgrade Program - Turn-in Sol-Ark 15K for EG4 18K

I see there is quite a bit of piling on here. But my 2c if anyone cares. I would not trade my 15k for an 18k "pv". I believe the EG4 product has a smaller continuous inverter, so its a bit odd to call it an "upgrade" program. But to each their own.

Personally, I wouldn't trade a 15k for two 18kpvs.

My friend’s batteries worked just fine with Sol-Arks in closed loop.. Not on any list, but he said the BMS is same as what the SOK brand batteries use.

There's been multiple threads where people have had failures of the eg4 BMS. I don't think it's unreasonable that solark is nervous about eg4 batteries being hooked up to their rebadged Deyes. The last thing they want to do is spend support resources engaging in troubleshooting for eg4 BMS failures, balancing issues that could take weeks to resolve etc.

Some talk of significant failure rates:

Thread 'Signature Solar EG4 battery BMS failure'

One of my 48v batteries died and would no longer even power up. I called Tech support a number of time and finally was assigned a tech, Trevor Wooden, on November 2. The voltage was around 30v and even though their BMS program indicated it was connecting, it didn't show any battery information. The battery would only charge to 50v. After two weeks of failures to change the situation, Trevor "escalated my case to a tier two tech named Victor. On November 23, Victor had me once again try to get the BMS to respond without success. Victor decided the most likely problem was that the BMS failed...

Thread 'EG4 LifePower BMS and Signature Solar Support Issues'

We have a couple of systems from Signature Solar, all similarly configured with Lifepower4 batteries and Growatt 5000 inverters. One of our systems (with a 6 battery bank) has been acting strangely, with State of Charge going down faster than we would have expected. Last week, we arrived on site and the whole battery bank was drained down to 0% SOC. The inverter was off, but no breakers were popped. We believe we've isolated the issue to one battery, and have been trying to communicate with Signature Solar for support on next steps. @SignatureSolarJess has been very helpful, but we...

Getting 2 things to talk to each other is not trivial. Android and iPhone still don't work well together.

If you want closer loop, then get approved equipment. Otherwise, open loop works just fine. Why not blame the battery manufacturer if the battery doesn't talk to the inverter.
 
You might want to read the thread comments again and refer to their PUBLISHED battery compatibility list. Doesn't this list represent closed loop compatibility? If it's not a list of closed loop batteries, then what is the purpose of the list?

Before passing judgement, suggest listening to the call that caused the commotion. I side with the SA tech vs the solar co owner. Painful to listen to someone who constantly tries to answer his own questions…
Link to recorded call on Facebook.
Recorded call
Conclusion: only in closed loop, and if EG4 bms caused damage to inverter, it could void warranty. In open loop, no issues. Seems reasonable to me.

Btw, I’ll gladly offer 2k for any working 15kW SolArk. Pretty sure the bidding will get closer if not over 4k though;)

Edited to mean solar company owner, not the solar equip owner.

hmm, works on all my devices. Here’s the link.

Also, I edited my previous post to correct that the caller is from the solar company that did the install and not the solar equip owner.

As you are attempting to make a contraction using Hezbollah, and Sol Ark, you need to spell it as Hezlark. We no longer use Hezbollha as israel removed their Bollah's with the Kosher Pagers...

You'll prob want to consider Midnite Solar Rosie and related units in that case if you need UL compliance, otherwise Victron.

Eg4 inverters at least in the past have indeed had very short lifecycles before discontinuation.

Nailed it Brucey, I was being sarcastic in my post but it was pretty subtle. I have not been impressed so far with EG4 gear or any of the other AIO HFs.. I have worked on a few for neighbors, then all the stuff you read and see. Hopefully the 18k works out better for everyone cause EG4 is popular.

I'm 100% off-grid and have zero code to worry about. No UL requirements. I only buy Victron gear now. They offer the best of both worlds in their inverters, efficient and reliable. Not as much grunt as a classic LF but way better then an HF. I know to much about inverters and could never buy an HF. Victrons toroidal setup is genius. They have found a sweet spot between the old bomber LF with laminate core transformers and higher efficiency HF inverters. They also have a really simple design with fewer parts. No massive front end filter messes like on an high power HF and the MOSFETs don't get constant torture.

Our initial units were made here, but then people kept saying that the newer units were made here as well. Even after correcting them, they kept stating that but rarely...sometimes you can't correct enough. However, we are bringing manufacturing/Assembly to the USA.

I was but have since moved on from that position. Just updated the Bio. I am always interested if people find misinformation on the site or elsewhere. Kind of like mystery shopping. Have you seen any claims to being made here in the USA?

Maybe a few hundred bucks to ship the unit alone! Ouch.
