I recently got a solar kit for house backup, lotta blackouts during summer, neighborhood running the AC.

One reviewer said power tools blew out the battery, guess it was drawing too many amps at once?

Wondering if the same thing applies to strobes? Do they draw alot of power at once or does it hold the flash charge in the capacitors of the unit itself? Specifically using profoto acute heads with generator pack. Would monolights draw less power?
I'm not all that great with electrical usages and scared to try with expensive equipment.

That sucker is $1,800. Why on Earth would you ever consider using such a device when there are countless other items on the market, specifically designed for work with photography strobes, at a WAY cheaper price. Hell, you can buy FOUR Vagabond Extremes for less than that.

I bet it took you much longer to write this than it would have taken you to read the very first sentence, where the OP says he bought as a house generator backup.

OP strobes will be fine. Tools consume much more than strobes do.

Before you use your strobes with the system you need to make SURE thet the systems converter produces PURE SINEWAVE output. Square wave output produces spikes at the corners and can damage fine electronics.

One, the profoto battery pack is $8,000 so its a potential good compromise on price.
Two, its solar chargable so I can be out in the field almost indefinitely
Three, I can use it for other purposes like powering my fridge or recharge my laptop 20 times
Four, the Vagabond is rated 158.7Wh, the Yeti is rated 1200Wh, so it actually has capacity of 7.5 Vagabonds

The Vagabond is designed for Alienbees, which are all monolights, there's no guarantee it will work with generator pack/ head systems. The highest powered alienbee I see is 640 Ws. Some of the profoto heads range from 4000 - 9000 Ws
What that translates to in terms of power draw I'm not sure of.

I would also question the price.     Only 60 watts of panel capacity?
4-8 days charge time (40-80 hours sunlight) to run a fridge for 12 hours?
That capacity is easy to put together

Less that 1500 watts.
Any standard wall outlet has a 15 amp fuse or breaker on it - 1650 watts - hit that and it blows. That is why a typical room heater is only 1500 watts.

as an example
Elinchrome RX2400 (120V)  is 30W  when switched on  (BUT with a 940W peak draw when charging up)
