Hi Andrew,
Any phrase that includes “per hour” while describing power use, generation or
storage in a RE system is probably a misnomer. Think about it: you could just
as well say 25kW per second or per month. That’s because kW is a term that
describes a rate or power, not a quantity of energy

Victron has the Quattro 10kW inverters w/ 100A pass thru and they have a good
battery management for their Li battery line. They have also started to have
their products UL listed. GOOD robust product and good support. Allen formerly

I think Outback is the only major inverter manufacturer that can do split
phase 120/240 to that size. You have to go 3 phase for 36 kW continuous
capacity with either Schneider or SMA.
Good luck, sounds like a fun system to design.

This is slightly larger than some of the systems I have worked with

Do they know what they are asking for? I'm/sure/ they have filled out a

There are many large 250kw to multi mw battery based inverters that should
cover this project.
Most are coming out of china, so I don’t know if UL is something they have.
Princeton is one here in the USA, looks like 250kw and 500kwh is their largest
on the web site.

A tough assignment, but Daryl has the right idea.
A company I used to work for did large off grid systems and would use something
they called a rotary capacitor (or something like that). It was a large
induction motor paralleled into the grid. It had a DC pony motor and some
synchro
We're not too worried about reducing the surge at this point; the
existing soft start controller is currently programmed for a fast start,
because their electrician was worried about motor damage if the
controller was set to limit current. It is currently surging to 700% of
run current, so we
Agree with Daryl here at the end. You have to solve the motor surge with
variable frequency drive and go 3 phase. If there is a reasonable cost to
use the grid I would not even bother with quoting an off the grid
solution. It is what the grid is best at and batteries are the wrong way
for this.
you have a problem that is much bigger than I work on. But on a large
motor heavy starting loads problem, we used an extra capacitor on the DC
bus of the frequency drive. the drive on its own greatly reduced the start
surge, if the load can be started slowly. If the motor must ramp up

Hello wrenches,
We have an opportunity to install a very large (60 kw) off grid system
in Mexico. It is currently three phase. I do have the option of
changing out the air conditioners (36 of them) to 120 single phase, but
it is an added layer of complexity/cost that it would be nice to avoid.
