SRNE 12kW IP65 HES and 10kW ASP

[Crowz]

Do you have a grid connect agreement or are you flying under the radar. . Id like to borrow from the grid when needed but im concerned about backfeeding into the grid.
Have you tried starting the 5 ton AC without the soft start with the ASP?

I'm running using the grid and have not had any back feeding problems at all with mine.
My sungold is an asp clone.

Do you have an electronic power meter?
I have a new one. Its remotely accessible. I believe they can even disconnect the service remotely by triggering the meter.

Electronic and commercial power meter. My house was used as a daycare right before I bought it and the power company had put in a commercial meter.

Huh, thats interesting. I know some commercial meters can track peak demand so they can charge for kwhrs and max demand.

Almost all smart meters should have that capability

I believe my utility company does detect power backfeed. Previously I tried one of the portable systems (which was not supposed to have backfeed capability) and was surprised to see my utility company's online graph suddenly showing a new category (power fed back to the utility). This only happened sometimes, and the amount of power fed back to utility was always shown as zero. This happened only during the times I had the portable system connected, and thankfully I did not get any queries from the utility company. This never occurred with EG4 6000XP nor SRNE ASP (configured in SBU mode, which is the only mode I've used).

I have not tried using the ASP to start the 5-ton AC without the soft starter. Using a basic clamp meter (one that doesn't have the accuracy to capture the true peak), I saw at least 25 kW surge power before installing the soft starter. I would not want to try that with only one ASP.

What brand of soft starter are you using on your 5 ton ac?

Decision Time:
-Two 12kW inverters (upgrade for my current 3x MPP6048's)
The HESP model 48HESP120U200 is quoted by Borick at 1,698USD plus ship
The SEI Series12k-UP (rebranded sold by others than Borick) is quoted at 1,658USD plus ship.

The net difference for me with shipping will be $396 USD (on two 12kW inverters).

So the question: Is the SEI exactly the same as the HESP - or could there be (regretable) differences in function, software, support, compatibility with solar assistant that the SEI will then disappoint?

Meanwhile, I will ask Borick to price match...see what they say.

Borick should be able to confirm whether the SEI is the same as HESP but without the SRNE logo. When I initially contacted Borick for ASP price quote, they sent specs on both ASP and SPI and indicated that the SPI is ASP without SRNE logo.

I was told the same. The SPI and SEI are 'white labels' .

 

[OffGridForGood]

Thanks for the confirmation guys.
If Borick will match, they will get the order, if not, SEI 12K-UP it is.

I was completely forgetting about this SRNE HESP48120U200-H inverter option of late as I was so interested in the HV Solis S6 11.4k-US. But the HV stuff might still be too early days for use here in Japan.

The SRNE however I'm told is certified and quite popular here in Japan. So I'm going to see if we can get this certified for grid-tie here. It's much better feature wise compared to what most solar installers are offering here as their standard inverter choice.

I like the fact this thread has 44 pages on it. Seems like it has a following and therefore community support and experience. I need to read back through this thread now.

Anyone with the HESP48120U200-H 12k model? Like it? Grid tied? All works well? Great unit? Thanks.

Edit: I've been told by Borick on 9/21/24 when I asked again to make sure, that it's actually NOT CERTIFIED for grid-tie use here in Japan after all.

12kHESP 48120U200 @apctjb has a pair of these IIRC. maybe this will bump him and we can ask about fan noise level as well.
I ordered a pair but will not be here until October - no hurry for my upgrade, because meanwhile the MPP's work perfectly since day-one, I just want more wall space, more max output and less standby idle, {plus I have some other places for two the the 6048's to go, where their output will work fine and give me 120-240 with a single inverter at each location.}

The more I read on this one I think I might be able to put it to use if the price is decent.

Still can't find one for sale though.

I'm curious too. Might shoot Borick an email if someone else hasn't. Specs, excluding output, very similar to ASP.

Be really interesting if they had a couple features for mobile applications. Could toss this and a couple of 48V batteries in the RV, use the 12v to feed the ASP idle consumption. Or a mobile battery.

You all have corrupted me! My system is still under construction, I love working on this stuff, and I'm broke. Thanks.

Did you order the SRNE 12k from Borick after all?

 

[gotbeans]

Huh, thats interesting. I know some commercial meters can track peak demand so they can charge for kwhrs and max demand.

are you confusing this basic thing that is in many meters with the commercial meters that track induction loads and charge for that, even when not using power? which is actually pretty unique for commercial (but mainly industrial) buildings?

The meter I have can do it all. Peak load, backfeed detection, Kvar and Kw load. Basically everything. I dont get charged for peak load or kvars ( power factor ). Only kwhrs.

Hello everyone. Update time.

I received my SEI-10K-UP inverter in Mexico without issues or scratches on the unit.

I installed it - grid-tied, 5kW PV panels, DIY 5kWh battery - and it works as advertised.

One quirk I have with my POCO here in Mexico is that I get two legs of a 220Y127V AC three-phase system. Lo and behold, the inverter works with my grid as described in its user manual - its settings support choosing either split-phase or three-phase (two legs), and one of several voltages per leg, the highest being 127V AC, just what I needed.

The two cons I've found are:

1. It's noisy. A droning buzzing sound that's continuous during the day, comes up for short periods at night. If installed indoors and its room's door is closed you can still hear it from outside the door, though it's much less annoying. Eventually I'll move it outdoors under a roof.

2. When working without a battery (just the PVs) and there's a blackout while the sun is shining, it shuts down and restarts - possibly because I only have 5kW total PV. Then when it restarts under PV power, it shuts down and restarts again almost immediately when it detects there's no grid. One way to break this loop is, in the second or two after it finishes booting and before it checks the grid, turn off its inverter operation by pressing its physical button on the unit's bottom, which makes the unit not shut down and restart when it checks the grid. Then in its settings change it to off-grid operation, and then turn on its inverter operation by pressing its physical button again. And given my limited PV power, I have to bring up my house's circuits/breakers one at a time so a single big, short power request doesn't exceed my PVs' capacity. This way my home has electricity from the PVs during a blackout, but I have to frequently check if the grid is back so I can return it to grid-tied mode. Luckily and importantly, this doesn't happen with the 5kWh battery connected to the inverter - if there's a blackout, it gets power from the battery soon enough to avoid a shut down and reset due to an undervoltage on the load side, and with all of the house's circuits on.

All in all, I'm happy with this inverter, especially considering its cost vs. the other options.

Anyone update to the latest SA beta?
I see they added a remote on/off switch for SRNE and Deye.
