It turns out that you can get access to the Solar Assistant data. Today I was frustrated that the 'group by' dates on the Totals tab didn't align with my Energy Provider billing dates, so I went down the following rabbit hole. Many of the following notes are known by many, not sure if it's...

This is an expansion of a previous thread I posted about using ESP32 devices to access RS485 data. The first thread, where I configured RS485 data access to Cell-Level data on my Riuxu server-rack cabinets, is here: https://diysolarforum.com/threads/esp32-rs485-inverter-battery-monitor.90937/...

There's some interesting movement on RS485 monitoring of inverters/batteries. First, I've found this github which will encode an ESP32 with an ESPHome configuration for controlling a SolArk. This would give full read/write control of a Sol-Ark 15k with an Open Source, Open Home foundation...

I'm in the process of acquiring the large Ruixu server rack. It's 10 48V 100Ah server racks assembled in parallel. It'll be paired with a Sol-Arc 15k. I'll be attaching a fuse to the rack for safety. Currently I'm planning a 350A class-T fuse, the Bussman JJN-350. This has an AIC of 20...

A month after AHJ inspection and PTO, I am learning my Tigo system was not installed properly. Currently I have the Tigo CCA pulling power from SolArk pins 15 and 16. Installers did not install a shutdown button. They said if the SolArk fails the system will shut down, and If I wanted to...

Is there a good source that explains the magic behind the All-In-Ones, like SolArk 15K ? I'm curious. My Sol-Ark will often pull 15 or 25 watts from the Grid, even at times when I wouldn't think anything difficult is taking place. Less frequent rapid pulls of a hundred watts occur too...

I took apart my system for some maintenance today, noticed some oxydation or other fouling behind the Class T fuse. Is this common? Something to be concerned about? This fuse is protecting 50kWh of battery, feeding to the SolArk 15K.

Has anyone had experience mounting solar to an Off-The-Shelf DIY pergola/carport? I am in Atlanta, that means I have very little snow load, (biggest snowfall in 80 years is 2 inches), and I'm in a well-protected valley, so wind limits are pretty low too. Something like this...

I am seeing periods, often 30 minutes or more, where the SolArk does not udpate the touchscreen or connected apps. For example, still reporting max-PV after clouds roll-in. On connected systems like Solar-Assistant, or the MySolark app, I can see the lack of data as well. Is this a common...

I have a system with 26 REC 420 panels, Sol-Ark 15K, Ruixu 50kwh battery. I also have 4 brand new 12V panels (250w) still in original packaging sitting in my garage, waiting for a Van project. My van has been delayed 6 months, and it might take another 6 months. Or longer My van plans...

I am looking for a quiet solution to maintain my 12V 200ah Office Backup, which is setup as a DIY UPS. I have a - 200ah 12V battery - 2200 watt Inverter - Victron Smart Shunt - Automatic Transfer switch. These keep Router/Internet/laptops/microservers up and running for 24hrs. Great! The...

I'm looking to build my first battery. I've noticed some BMS's, like Daly, will have leads and all the system load will transfer through the BMS. Others, like REC BMS, only have sensor leads to monitor cells, and don't carry the system load. Are there advantages to one style over the other...

Designing an 8S 24V with MB31s. It will have a T-Class fuse. My question is I also need additional disconnect, and what that will be? Let's assume a JK Inverter BMS, which will have a BMS switch. It seems like adding breakers, to be used as switches, is also common. It does feel helpful...

I am building a structural battery pack with 8 MB31 and a JK Inverter BMS. Screen and comms will be mounted on the side of the battery. I have highlighted the BMS in Red to show the planned location. Walls and top (not shown) are 1/2 inch (12mm) birch ply with laminate covering. This leads...

I'm considering the Lynx Distributor for my 48V system. One challenge I see is availability of fuses. Lynx Distributor uses Mega Fuses. While limiting myself to only reputable storefronts, I see a VERY limited number of options for 48V Megafuses. Here's an example...

I am building a electrical system for my RV. Batteries will be 2 separate 8S 24V 304AH with Eve Cells, wired in parallel. They will be in separate cases for redundancy. I would like to be able to operate with one, or both installed. I expect max current-draw will be 130 Amp. It is...

In some older posts I see a reference to a max Watts of 6,500 for each MPPT. I also see in their String calculator at https://www.sol-ark.com/resources/sizing-tools-calculators/battery-inverter-sizing-tool In the current tech-specs for Sol-Ark 15k, They mention Max. DC Input Voltage: 500...

I have built a small "UPS" using a 100ah 12V battery, and a 600W Giandel inverter, and a Xantrex Prowatt PS automatic transfer switch. https://www.amazon.com/gp/product/B004S5Y158 The Xantrex does not share a common ground accross the legs. Thus when I'm on battery, the inverter is not...

Hello, I am looking to monitor the energy generation from my B2B system. I was assuming I could do this with a SmartShunt. However, these can only be attached to negative lines. My van uses a Chassis Ground. The Lynx Distributor grounds the negative busbar to the chassis, and likewise...

I'm looking to build a battery for my RV. I do like the ease of the off-the-shelf cases that come with everything, but they all come configured for 48V. Like this one: Has anyone taken one of these and configured them as 2P8S for 24V? The BMS does support 24V, but will the packaging work...
