Form 5695 Qualified solar electric property costs

I installed solar panels with a battery and was given a total price (not itemized) for the entire system.

I put that amount on Form 5695 line 1 Qualified solar electric property costs.

Line 5a and 5b refer to Qualified battery storage technology costs but I don't have a way to separate that cost from my system cost. 

I checked yes for line 5a (greater than 3 kWh) and $0 in line 5b.

Will that work?
