Hello, all ... I've an array of 10 Hyundai HiS-M300TI panels that I bought used. While 5 of them work well, 2 are only so-so and 3 are definitely underperforming. I have no shade issues, so I think it's the panels themselves. Anyway, I want to replace the worst of them, and if I can DIY, even...

Hello, all ... I have a Fortress Power eVaultMax (18.6kwh) connected to a Sol-Ark 8k that works well. I also have a BigBattery Kong Elite Max (19kwh) that I want to connect in parallel. The chemistry is the same (LFP). the cell config is the same (16S), but the charge voltage recommendations...

Hello, all ... So, PG&E finally inspected my solar upgrade today, and they found one issue - the installer ran conduit within 2ft of the gas meter. While I'm confident that I can hire an electrician to get this corrected quickly, I'm wondering: Does this kick me out of NEM 2.0? The application...

Hello, all ... Can anyone point me to a vendor from whom I can purchase 10 Trina TSM-DE19 550w panels? I'm in northern California. Regards, John

Hello, all ... I _love_ my Sol-Ark 8k. It's awesome. I have it connected to a Fortress Power eVaultMAX - also awesome. Those being said, i've an issue where the Sol-Ark doesn't automatically switch over to battery power when the grid is down. The grid wires from the utility breaker are...

Hello, all ... I've a Sol-Ark 8K connected to a 48V 18.6kwh 360Ah Fortress Power eVaultMax. This works well, though I also have 3 48V 5.3kwh rack-mount 103Ah LFP batteries from another manufacturer. From what i've read, I can't put these in parallel with the eVault bc they're too far apart in...

Hello, all ... I have a Sol-Ark 8k and a Fortress Power eVaultMax, and they communicate over CANbus. Since I think this is really cool, I'm looking to add CANbus to some other batteries I have, so _they_ could also communicate with the Sol-Ark. However, I don't know the specific CAN messages...

Hello, all ... As a personal project, I'm looking to power a microcontroller from a 48V LFP battery (BigBattery LAMA). The interesting thing is that if the battery is discharging, I want to power it from the LAMA, but if the battery is charging, I want to power it from the charge controller...

Hello, all ... I have a 6kw PV / battery grid-tie system using a Sol-Ark 8k and Fortress Power evaultMax battery. If the grid goes down, I want to be sure I don't backfeed the grid, so I think I need a xfer switch. My neighbor suggested the Generac CXSC100A3. Will this work with my system...

Hello, all ... I'm looking to expand my 6kw PV / battery system (consisting of 10 Hyundai HiS-M300Ti and 11 SolarWorld 275m panels). To make it really easy on the installer and be assured that they'll work with both the panels I have and my inverter, (Sol-Ark 8k) I'd like to get panels either...

Hello, all ... I purchased a Sol-Ark 5k this past August 2021, but recently upgraded to an 8k. The 5k worked very well, but it's limited to 6kw of PV (which I have) and I wanted the option of expanding should I need to. I paid ~$5000 including tax, and I'd like to sell it for $3500. I'm in...

Hello, all ... The installer installed the CTs for my Sol-Ark 5k today, and after that (at least, earlier today) the Sol-Ark was indeed showing the power draw from my home. Now, though, it's dark outside and yet my Sol-Ark 5k shows that there is no solar (expected), but i'm still feeding the...

Hello, all ... I've a Sol-Ark 5k connected to a 48v 5.3kwh LFP battery (the Lama from BigBattery.com). So far it seems to be working, but I've questions: 1. According to the Powerview app, the Sol-Ark only drew .2kwh from the battery between the time the sun went down and now. That seems...

Hello, all ... For grid-tied solar, how does battery size impact the size of the PV breaker on the main panel? My current PV breaker is 20a (which handles my small 3kw array) but i'll need a 30a breaker for a 6kw array. This makes sense (6kw / 240v is 25a, which is within the limits of a 30a...

Can anyone recommend reputable online resources for solar plans? There are individuals on Craigslist advertising them, but color me skeptical when their website doesn't work ("but you can just send me the $ directly"), other ads on Craigslist have the _exact_ same content but a differently named...

Hello, all ... My home has 100 amp service from PG&E and I have a small 3kw PV array that came with the home that I would like to expand to 6-7kw. In a previous home, I just had the main panel upgraded and all was well, but with this home, the electrical service from the utility is underground...

Hello, all ... I purchased a home recently with a 3kw PV system using a Delta Solivia 3.8TL inverter. I want to add another 4kw, but the original installer is no longer in business, and I want to use the current 3kw system to help charge the batteries should the grid go down. Everything I've...
