Been on solar for near two decades now, best most reliable power I've ever had, and it's true sine wave, very clean, and not overpowered, doesn't hurt old tube gears designed for 117V, which is exactly what it's running right this second.
No sun right now, raining but the power's holding fine.
It's like a ship, with a power center, and I being very automotive, I love that it's a 12V system, can read the voltage from bed, right now at 12.6V, which is fine. During the day we get up to 14.9V even over 15V if equalizing the batteries (automatic), and that's pretty hot for 12V batteries.
For a $720 in new panels a few years back, we're able to run 2 large fridges and a fully stocked freezer 24/7, the same $1200 ProSine inverter doing the job reliably since bought new bout 18 years ago.
Don't buy Harbor Freight junk.
Imagine, not having a power bill?
I'm not very grid friendly, an aging monstrosity that needs to be buried as it constantly starts fires and more.
Not only we're off the grid, but there's no grid power within miles of our house, no poles/lines to crash into trees, really lowers the anxiety levels for me.
Last raging fire we had here, started just a few miles down was a power line crashing on a tree as a lady drove by and saw it. Burned 600 acres in one day, people lost pasture, fences, cows, barns, houses.
Then the lineman come, put it all back up, the heroes, and then you just wait for the next one. Thanksgiving blackouts that last 2 weeks, etc.
No thx.
