RE: Question
I found this, and it agrees with your statement above:
Question:
How much energy does this unit in $ amount, suck out of a wall socket to charge 4 -20-6 ah Flex Volts in a single charge cycle? how fast can it charg
Answer:
This unit draws up to 3 amps of current when charging 4 batteries at once. It charges up to four 4.0 Ah battery in about 2 hours and a 6.0 Ah battery in about 3.

So you would need around a 360w Inverter, minimum. I've seen 350 but that is running it too close, I'd use a 750 just for giggles. The solar panel looks to be ~100w capable. Directly feeding an inverter with a solar panel is not usually done unless you have a lot more solar output than the inverter needs, UNLESS you have a battery bank between. You'd need more than one panel to feed the inverter, without a battery bank in the panel to inverter chain.
Personally, I'd use 500w of Solar, feeding a 400w Inverter, then the PPS. If you want to use less solar panels, you definitely need another battery bank. Then sizing changes again... but a smaller panel arrangement can be used.
For the LiIon cells on the PPS, I'd get 2 sets of THESE:

$206 per 2 batteries, 20v/60v Flex Powah!
thanx
why would it matter if the solar panel output is too low?
a spoon scoops just as well as a grain shovel...just takes longer.
In my experience, they just shut down and do nothing. Most of these things put out a lower voltage, which causes a greater amp draw. As you may have noticed, the panel delivers 17v nominal to a 12v rated inverter... The inverter can work with a voltage "range" but at lower volts, it needs more amps. If we have limited sunlight, the inverter needs more amps and it usually just goes into alarm and shuts off shortly thereafter. 17.7v times 5.7 amps is your 100 watt rating, (100.89 to be exact) Electronic regulation makes the outputs stable. 4 series Lithium Ion cells, multiplied to get 35 amps out would make the small Solar Panel work great, but that adds a lot of expense. The PPS is made to hold a lot of charge all on it's own, perhaps just buying 2 whole sets (8 batts) of the DeWalt Batteries is a more feasible and economic situation? Less flexible, but cheaper.
er...no.
the PPS doesn't have any internal batteries....
I meant the drill batteries. Get at least 8 of those big 9.0AH ones and forget about the solar panel and extra inverter ;)
Here's that link again:

That plus your smaller ones with the tools you already have should do the trick all day I'd think. Then maybe solar later? lol
Those are LOTS Cheaper than the Milwaukee Red Lithium 9.0AH batteries I saw locally, $179 each! OUCH! $103 for the DeWalt
when I got the PPS it came with four batteries...
I already had two so that makes six total now.
those suckers are EXPENSIVE..the big one cost $100 each.
the one I saw with batts had 3x 4AH and 1x 6AH, but the link I provided is 2x 9AH for $206 and the run times for the PPS would be a lot longer. $412 is a lot of fiat but it is immense back-up power.
The new DW lineup is pretty impressive!
I got a literal crap-ton of Li-Ions when Radio Shack shut down, like 32x on the 26650 cells, I need to build a back up power pack with that, I think ;)
yup...I would.
there are u-toob video's about folks doing that very thing.
A spot welder is much better than soldering on to the end plates of the cells, (as many U-TooberZ do) I am thinking HARD about getting one ;) I think my retirement job is going to be Battery Tech Deluxe :D
