I have for sale a pair of off-grid inverters for sale - 2x Sunny Island 5048 units which have updated software to support SOK lithium 48v and lead acid. Was in a permitted off-grid install. Also includes an SMA6000US inverter (7500w) max. Asking $3000 for all. In Chico, California. Has...

Hi, I have two SMA 5048's sunny islands located in Chico, CA. Went with a different inverter option and was planning to use them w/ my existing SMA7000US inverters. The best off-grid inverter hands down if you live off-grid. Asking $3500 for the pair. Not sure about shipping these. Zip...

I am in the process of trying to permit a 20kw+ system in California connected to PG&E. The local municipality will let me use my existing SOK batteries from my other residence (have about 30kw worth) in an outdoor enclosure w/ UL9540a on the 48v SOK rackmount batteries. I want to purchase the...

Hi, I recently had a power outage of 4-5 days in Northern CA, and our sok48v six stack (31kw) + solark15k kept us running the entire time, even with lots of rain using the 8kw solar array and currently the external generac lp is not working. Might be looking to buy another solark 15k and...

Hi, I have an old SMA7000US connected to the load side of the solark15k and it's working great with sok batteries. The pvpro software does not show any estimates of pv production and the main screen on the solark does not know either. I do have an rs485 card in the sunny boy and was curious...

I currently have a pair of sunny islands si5048's and a pair of sb7000us/sb6000us which are grid-tied. I was curious if it was possible to use another inverter on the AC1 side of the sunny islands like an off-grid EG4, growatt or similar and how they sync to the main signal for single phase...
