    Ground mount recommendations

    That is where pounding and welding an array out of steel pipe would work much better than the sinclair. Contact a fence builder.

    Ground mount recommendations

    Video of the sinclair ground mount system in action from Engineer 775 (this guy is very respected and knows what he is doing). The video is about the Solark 15, but in it he shows the ground mount sinclair being driven directly into the earth. The sinclair system is engineered, and on an...

    PV String DC Voltage Limiter

    I understand your written description - now I just need to learn to read and build the diagram. Thank you!

    PV String DC Voltage Limiter

    I think I crawl up on the roof one time when the neighbor (local utility engineer who approves the solar permits) isn't around and figure out how to rewire the strings without removing panels. Just leave one panel in each string unconnected.

    custom made battery box for eve LF280K cells

    I did read the BMS manual. I was aware of the fact it takes time to learn the behavior and capacity via multiple charge/discharge cycles.. I was providing a review of my experience with the battery (as requested), and verifying the experience and documentation match. I was not criticizing the...

    custom made battery box for eve LF280K cells

    That is what this entire thread is about. The seplos battery kits were designed in response to sergea's request. My understanding is he footed the cost of the engineering for these kits. That we have them at all is a reflection of his willingness to share his idea with a company and pay for...

    Sol-Ark 15k Operational Impressions?

    I ran it for a few weeks without batteries as a dc inverter, and ac pass through. It worked, but had a few minor issues. The solarak support was friendly and helpful, and they are the ones who insisted things definitely work better with a battery. Once my batteries were built and attached all...

    Sol-Ark 15k Operational Impressions?

    Get a seplos Mason kit and build your own batteries. That is what I did for a fraction of the price of the prebuilt units. It will work better, and allow full control of any parameter you need. More capacity, higher quality, higher charge and discharge rates, better control, and cheaper...

    custom made battery box for eve LF280K cells

    The state of charge is not exact. It took several days of complete charge/discharge for the bms to learn the capacity. It is getting more accurate every day. I have all 4 boxes in parallel. The inverter will report a charge value and the 4 boxes will all have different values, that average...

    custom made battery box for eve LF280K cells

    Have 4 boxes currently in service. They work as advertised. Charging to 90% and discharging to 10%. Only issue is the battery bms kept changing the desired charge values on the solarak inverter. I reset the charge, float, and equalization values via the solark, and it was changed the next...

    custom made battery box for eve LF280K cells

    They claim their custom cables use 50mm wire. The 6.0 connector tops out at 25mm and 125 amps while the 8.0 connector goes from 25mm-70mm and would fit the claimed wire size and amp draw. I sure hope they are the 8.0!

    custom made battery box for eve LF280K cells

    Has anyone successfully purchased the futronics connectors to make your own custom cables? I think they are these ones: https://en.futronics.com.cn/product/88.html but would like to be sure before I order them. Seplos will not confirm the connection type or any other details. They took...

    Sol-Ark 15k Operational Impressions?

    I have a basement install on the common wall with the stairway. You can hear a little noise in the stairway adjacent to where the inverter is mounted if the fan is running. It is slightly audible through an unisunulated 2x4 and drywall walI. You don't really notice it when it is running...

    Sol-Ark 15k Operational Impressions?

    Mine has been up is a dc coupled and ac coupled mode. Had a few issues solark support was quick to help with and resolve. The grid sellback setting is a little inaccurate. I am allowed to sell back 10kw. When set to 10,000 watts I was sending back around 10,600, with periodic spikes up to...
