Battery Neglect

It's been a while since I filled the batteries that are part of our PV Solar system. We have 24 giant lead-acid L16's and they take about 8 gallons of water when they need to be topped off. Instead of using the old plastic watering can I decided to try a siphon system. This worked pretty well just using $3 in tubing combined with a little squeeze pump I found at a yard sale for $1. I'm transferring rain water from a 4.5 gallon plastic cubby.

I hope you filtered and then distilled that rainwater before adding it to your batteries. Impurities such as dust particles will dilute your acid solution and possibly cause sulfate buildup along your lead matrices.

I do a PPM test and let it settle over night. Usually I seae a reading of 30 PPM which is pretty good since distilled water from the store is about 15 PPM. You are right though proper distillation would be the ideal thing to use.

Have you ever checked out Quick-Fill Watering systems? I was wondering if they would be applicable to a solar installation.
