Looks like SQD advertises the same thing, but the 1ph vs 3ph is probably a problem with the NEC. I'd like to find a code-compliant way to do this.

AFAIK, this is really the only interlock available that would make sense as most of the others appear to be design to be mounted directly under the main: This meets NEC 408.36 Overcurrent Protection (D) Back-Fed Devices. Plug-in circuit breakers that are backfed must be secured in place by a...

Do you mean NQ or from other manufacturers?

Need to find out how willing the SF DBI are to things like these....... AutoCAD

I've looked at my QO panel and it looks like 2 min with a grinding wheel can make it split bus, just need to remove the plastic, cut, then reassemble.

Yea, this is basically what I'm thinking Looks like one of the few still available: QOGP3P604436200P

Thanks for the suggestion:

The mechanical interlock needs to sit between the two breaker's its interlocking, so this means it has to straddle the split with the two breakers on either side. LMK if I've missed what you were suggesting.

yes

I'm curious if anyone has used a split bus panel and had it pass inspection. The interwebs points to 408.36 of the NEC but I don't see any issues with this setup so long as the backfed breaker has an additional fastener per (D) and confirmed by the manufacturer. This configuration would give...

Are there any places to get the DWG files of sample permit sets?

I thought I remember seeing something a while back that there is a modbus register you can use to control wether the load connected to the GEN CB is ON/OFF. Nothing on their communications list points to anything but their list is only a partial of what the OEM'd device actually supports. Does...

I reached out to them and asked them for some clarifying questions on their warranty. That was about 7 weeks ago in mid-July. I followed up after a week but that didn't help. Is this normal for them? Or is my email to their listed contact info on their website not accurate...

I've got a townhouse with two units on two different floors. They have their own individual utility meter and individual electrical systems. Since they share one roof, I'd like to understand if I can combine the DC PV cables from each system from the roof down to the ground where the inverters...

It looks like the megarevo is also a brand labeled unit, just like the EG4

They appear to have a newer line of these inverters which come in a unique looking enclosure. The case gives off fronius style vibes with the champhered corners and curves at the top and bottom. Their previous line of hybrid inverters appeared to be rebranded versions of sunsynk units. But...

I’ve got some LG batteries that have an integrated battery monitoring system that speaks CANBUS. I’ve never interfaced with anything over CANBUS but familiar with other protocols like modbus. I have an ESP32 with CAN capabilities but wondering if I need something equivalent to a modbus...

I've got these batteries but was trying to do the math to get down to the cell level. LG's marking says they're 3.2 kWh. And I've taken the units apart and seen that they are 14S 4P per module. I'm making the assumption they're using 3.7V nominal. So does this logic make sense?

Nice looking system! How are you protecting each of the 14s strings before you combine them and send them to the inverter?

If you want to extract more data from your system, you can spend 10 bucks on 4x wemos d1 mini’s and pull in the data into home assistant or MQTT via ESPHome: https://esphome.io/components/sensor/daly_bms.html

Cool, I'll check this out. @bixelps - Have you seen this?

Does anyone know if you can model the power flow like diagram in grafana?

Thanks again for the making the integration, it’s working great! Have you done any automation to your system and writing of registers to the SA? If you’re already storing the data in influx, it might be good to disable storing this in the default HA DB. I run a separate Postgres db for HA and...

1k miles for a reset is brutal. How did you get so low that you tripped on low voltage? No alarms or alerts configured? I run my system from 48v to 56. No issues thus far. My utility has forced us into TOU rates and I’ve selected the one with the highest peak rates so that I can offset them...

Good to hear. I’m also babying my batteries because my tiny solar array will only send about 22 amps into the battery at peak and I’ve limited my charging from grid to a similar 20A. I took another look at your battery configuration and noticed the smaller control wires through the middle. Are...

@tanoshimini @paulmurdoch Just curious how your systems are doing after some run time on them. Do you track any data?

Many times international packages will get delayed at customs. I've had this take anywhere from 3 days to 3 weeks. But the carrier's tracking info will say that it's in customs review or waiting for additional customs documents as they want the shipper/receiver to know they arent the reason...

I'm in PG&E territory, everything I've seen from them or CA typically requires the installing contractor to be certified to some program. Are there any that you qualify for if you do DIY? Just curious if anyone has been able to get them.

I just got a small 2kw array added to my Sol Ark 12k. Looking at the settings available, I can't seem to figure out the correct combination of settings to fully leverage all of the power out of the solar panels without pulling power from the grid. The Sunsynk training manual has a comment that...

I've got a sol ark 12k and can confirm it will sell export power from the battery if you so choose

Thanks for the detailed explanation. It makes sense that the base "load" of keeping the inverter's lights on are skewing my low load efficiency numbers. But I'm still curious what others are getting in this scenario where you're powering your AC loads from battery only.

power into inverter vs power out of inverter did you see the chart that's in my OP?

Just curious what you're getting on your battery systems...just be sure to post what inverter you're using I've got a Sol Ark 12K that's supporting most of the loads in my house. I've tracked the energy efficiency and it's approximately 90%. The CEC Efficiency is called out to be 96.5 in...

are you able to share your PCB design? I'm currently pulling the data via modbus using the component that another user here developed: https://github.com/pbix/HA-solark-PV

What data are you able to get from the wifi port? Is it the same as all of the data available via modbus registers?
