Hello. Reaching out to learn more about AC coupling with my existing Solark 12k system. I have a 10kw solar array being controlled by a Solark 12k (wish the 15k was available 3 years ago). I re-wired my home electrical to have all my 120v loads powered by the Solark 50A critical load breaker...

Trying to skimp and save the expense of a larger charge controller. As someone suggested, perhaps I should pickup a Classic 150 or FM80 and use 2 longi's facing East and 2 facing west (lined up with the existing small old panels). The extra power in the summer would be put to good use and...

Thanks for all the replies. I'll stick with the plan to add an additional charge controller and pannels. Since I have an extra Midnite Kid laying around, I will try that first and see if it provides what I need this Winter. Since the Kid only handles 30A, on a 24v system, I believe I can only...

Hello all. I have a small system for an offgrid cabin. Currently consists of a Magnum inverter ( MS402PAE), two Midnite Kid charge controllers (30A), a 750 watt East facing array, a 750 watt West facing array, DIY built 24v 360AH LifePO4 battery bank (the replacement battery is my doing...

Hello all. I'm attempting to install a solar pool pump and a solar well pump. Both pumps have identical DC input specifications and use a similar controller.

Hello all. I'm attempting to install a solar pool pump and a solar well pump. Both pumps have identical DC input specifications and use a similar controller. What I want to do is utilize the same solar source (say 2KW array) and have the pool pump run continuously when the sun is out except...

Thank you for the help. I'm excited to get this working. Still having communication issues between the solark and SH-U11f. I will post over on the repo. Ultimately, I will be plugging the SH-U11f in a TP link ac1750 running Openwrt (wired bridge) and mbusd. The ac1750 access point is next...

Hello. I have been stumbling around attempting to get a mdusd connection to my Solark 12K and ultimately utilizing the Home Assistant integration to read and display the data. Mainly following the information provide from this link https://github.com/pbix/HA-solark-PV As recommended from the...

Thanks again. The explanation helps. I did not see a menu option to Autostart the Generator, so assumed if the Gen Charge was selected (in Batt Setup) the autostart relay would automatically close when the start charging parameters were hit (regardless if connected to an autostart gen or not)...

Hmm Good to know. I guess I was trying to figure the differences Carlos was explaining between autostart Gen and manual start Gen. That is auto start opened the internal Gen breaker and manual start did not. Hence creating a possible back feed when AC coupled when auto start was not used.

Thanks for the above, definitely helps understanding the Solark software logic. Just a few more questions: I think I got it. I suppose if I did not have auto start generator, one could hook a 12 volt source up to the gen start pins on the Solark. When the software called for a Gen Start the...

Currently I running a 10kw 200ah Fortress battery. Would it be possible to add more similar batteries (I.e., 30 kw server rack) in parallel with the Fortress? Seems like this would work but not sure how to split the charging run from the Solark Perhaps a distribution block.

Thank you Ampster. Good information. Both MPPTs on my Solark are being used and cannot be added to. A new array with Micro-inverters for the AC couple may be the best method. I was getting greedy with the abundance of low cost hybrid Inverters that I did not know existed until recently...

Hello all. Ended up on this thread as I have a very similar question/issue (want to use AC coupling with my Solark 12k grid tied and have generator backup). The goal is to add capacity that I can sell and store in more batteries. I currently have my 8kw generator connected to the Gen Input...
