SRNE HYP series vs. EG4 3000EHV (HF series)

I had decided on buying some EG4 3000EHV units, but wanted to go OEM and get the SRNE equivalent so I purchased 1 unit direct from SRNE on aliexpress, and it arrived in 4 days, from HK via DHL. (DHL is lightning speed from HK this is typical)

The EG4 3000w appears to be a de-rated and rebranded SRNE HF4835U60-H (500v PV, 48v bat, 3500w 120v inverter, single/split/3-phase and/or parallel options).

Edit: the EG4 v1 is likely based on the HF series and the EG4 v2 is likely based on the HYP series.

Maybe EG4 wanted their offering to be 3000/6000/etc watts. I cannot find evidence of any SRNE model that matches the 3000w EG4 unit exactly in all rated specs, and they have over 20 variations, so I'm pretty sure the EG4 is a 3500w unit. Plus, it does not make sense for SRNE to customize a 3000w version for EG4 from a PCB manufacturing perspective, they would just sell them the 3500w PCB, possibly limiting the EG4 firmware by request to 3000w, and call it a day.

Reading the HF series manual, I discovered the 5000w version existed (HF4850U80-H) which was the new front runner. 50% more inverter output over the EG4 in the same footprint and similar price seemed obviously worth it.

Finally, exploring the SRNE website I discovered the HYP series, which appears to be the same footprint as the gen2 EG4 units.

Trigger pulled! I picked up the HYP4850U100-H for $675 shipped, the same price as the EG4-3000EHV-48 stateside with 50% more output per inverter.

I cannot test until my batteries arrive from SS, but i did take photos if anyone is interested in the unit.

yes the parallel connection is also different but comes with the cable and it allows 12 units total. 6 units total for HYP, vs 12 units on the EG4.

thank you @42OhmsPA. I have been a fly on the wall for about 2 months and the hook is set deep now.

I have tracking on my 2 EG4 batteries and rack, so i will be able to get the first inverter operational as a battery backup system next week for heat/lights/internet. I have been chipping away at the install area.

I have 3 phase from the street in my shop, and will have at least 2 arrays very soon, so I am planning (3) SRNE units setup in sync as 3-phase. I don't have anything that requires 3 phase but I want the flexibility to easily move 240v loads around the electrical panel to balance things out across any 2 of the 3 inverters as we upgrade equipment in the workshop. We run compressor banks, multiple laser cutters, water chillers for lasers, reflow oven/pick and place, lots of ventilation/exhaust fans/air filters, mini split heat pumps, EV charger, etc.

GRID sub panel is now live, inverter AC input connected, inverter AC output connected to BAT sub panel. I also had to take care of some other things in that utility area before moving the EG4 battery rack into place, but it's ready for the welding cable to connect the rack.

I'll have the inverter live Monday or Tuesday. I have a compressor bank and lots of things to load test. I won't have solar until I pull the trigger on a 20ft shipping container. That will likely happen in March, as will the other 2 inverters.
 
Thanks for following up and good luck.

I found them on the SRNE aliexpress store for $655 plus a coupon for $30 off if you spend over $100.
I'm waiting for a quote from SRNE Alibaba.
 
@42OhmsPA how are you connecting your SRNE and batteries to comms? i was thinking solar assistant on RPI. i am VERY familiar with USB-rs232 converters and RS485-usb converters, but it appears there are several ways to do this and even 2 different busses on the RJ45 battery ports.

I'm using USB from the SRNE to the pi and the overkill converters for the JBDs to usb to the pi.
No comms between batteries and SRNE.

Let me know if that doesn't make sense or you need more info.
 
I ordered 18 of the NE solar 370w panels, en route. The first array of (6) is going on our box trailer....potentially this weekend.

The remaning 12 panels are going on a 20ft container, before april. Those will also be arrays of (6) panels, each with another inverter.

I realize all 12 can go on 1 inverter, but we will have 3 so i'm going to spread it out.

I have 2 SRNE hybrid inverters HYP4850U100-H. 3 10kwh batteries all in parallel. 10-550w solar panels. Got it all installed over the past week. Wiring is still a mess. But because i bought the second inverter 2 months after getting the first, the firmwares are different and i get an error message when running 2 phase in parallel. Do you know how to upgrade the firmware by any chance?

1. I havent powered iton yet, but I would email them. They will want to help you so you buy more. I will be in the same boat when I buy 2 more, I will email them also.

2. I have to check the manual but I dont think our units need the loopback parallel cable. That might be an issue...I would unplug the 2nd one.
I think this differs from the EG4 RJ45 parallel links?

3. Manual says don't install on combustable surfaces like wood. I think they recommend rock wall.

4. Who makes those batteries?

5. Are you adding fuses to each unit on the 48v battery lines? I thought that was the norm.

6. Would love to see closeup of mounting...I am buying a container also.

1. They want me to confirm my versions first, which I did for them. My brother has a different brand and a rep logged in to his and updated remotely when he had a problem. That would be nice.

2. So I'm running 2 phase in parallel. This diagram from the manual shows those two cables. Am I wrong?

4. The batteries I got can be found here. I went through my Chinese rep so the label on mine is actually different. They were $1800 each. https://www.genixenergy.com/power-storage-wall/10kw-es-box5-battery-backup-for-house-powerwall.html

5. I have breakers for each battery. I originally connected batteries in series so I only had one fuse for all 3. Have since changed to parallel wiring so I need to add the other 2 breakers to each battery.

For the container, I used unistrut and mounted each foot on the side of the container. I ran 3/8" bolts through the top, between the panels if that makes sense. That way the bolt never goes inside the container. When I was done the unistrut couldn't support the middle weight so I added a bracket in the middle with 1 1/4" pipe. Here is a picture from a camera I have on my roof. I zoomed in. If you want to know more let me know.

No I was wrong, you have it correct. For some reason I did not think the end of the chainlooped back.
