A Sandi 30kw LF high voltage inverter in the future . Mike G latest youtube show his 25kw doing load test and do 26kw easy and all the wires are cool . A Sandi 30k will pay for itself in a few years . A Sandi 120vDC 12kw inverter will pay for itself for me in 2 years because of the stupid utility rate in Arizona . 40 cents per kwh for 4 months of summer and 10 cents for the other 8 months . Arizona has the worst net metering of paying 4 cents for grid-tie solar and it cost 40 cents to use grid power at night . Almost nobody get free solar like they advertise because the utility charge 100 dollars a month for maintenance fee . It is very difficult to parallel 240/120 split-phase inverters but more company are doing it with RS485 external cables . Sigineer has a 120vDC inverter now 15kw . GS is never going to catch up and Sean best to keep the full time job .
I see Sean finally popped up in a youtube video with more delays coming (yesterday).....their reinvention of a powerjack inverter-based production is still too slow with a slow undependable supplier...
Sigineer is a tried and true LF inverter design that is used by Aims, Yiyen, Sungold power, etc with off-the-shelf parts for the most part...vs the gs12 reinvention with no ability to do a load test.... for the claimed continuous working ability... the Sigineer can surge for 30 seconds longer in the 12k to 15k so would start extra loads... not sure what the 15k would do for surge....
Yes, Sean needs to keep his full-time job....family of nine with 60000 miles of driving per year....lots of expensive food etc....I seriously doubt they will ever compete with the inexpensive China labor price anytime in the near future or be able to keep up with the new equipment coming onto the scene...
The
Sandi 30kw high voltage LF inverter is the future....the high voltage runs cooler and as Mike G showed the wiring is fairly simple....the high voltage battery can be custom built for a fee...
Jack Riccard at EVTV Motor Verks commissioned them to redesign the Sandi LF inverter and I believe he was forward thinking....a pioneer to the large electrical usage of typical homes in the USA today.....
The people who think they can use a 5kWh battery to power much of anything or use a 6kw inverter to power a 24/7 house off-grid are being duped...unless they live in a tiny home like a hermit and do not care to live with modern convenient electrical appliances!!!!
Sounds like the utility company is a big rip-off to do a grid tie as well as their rates are a bit exorbitant so off-grid is the better and likely more dependable way for you to go.... besides the fact of a bunch of other expensive equipment to be grid-tied to give them the PV solar electricity for essentially pennies in comparison to what they charge you to use it...
South Dakota has no grid tie net metering so there is absolutely no reason for me to hook any solar PV-generated electricity to their grid...
Off-grid is definitely the best way in my situation!!! ???
Have a great Tuesday! you always have good information to share....Thanks
