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...

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?

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...

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...

I'm trying to figure out the best settings for my configuration. I've got a Sol Ark 12k paired with 14x of the LG Chem UPB 4860 modules. These modules have 14x series packs of 4x 15Ah parallel cells. David Poz has a great video on the modules. Below are the settings I'm using right now and...

I saw this on their site and wondering if anyone's actually seen one or had any experiences with it. The manual is dated 10/20/2020 so appears pretty new. Brochure & Manual
