Solar power without grid or batteries.

much better idea. get the panels you need. Inverter size and 1 to 2 lithium batteries. mount them on a trailer and drag it where you need power for the day.

load dependant a 5kw inverter means 48v brick
though a person can get a 2.5kwh battery halving the weight

There is no grid in this scenario.

many will start up even without grid
my off-grid kodak powers up from solar from panels if no eskom or battery(flat at the time)

once had this perfect storm

inverter ran but tripped overload everytime the solar dipped lower than load

Yes, those are called "grid-tied" installations. Most of the world is like this. Only SA do we use batteries.

if you use grid-tied you can only use the solar power if eskom is there (no shedding)

while if you get a hybrid, you can have backup power during the day direct from sun no battery needed even if eskom is gone, you only sacrifice night time backup without the battery

I was talking about the rest of the world who doesn't have the problem of the grid falling over all the time so they use the grid as a "battery". We need real batteries.
