You are going to need a much better charger, a multi-stage 20-30 amp one like a CTEK. Lets say you use your batteries down to 50 percent DOD, it would take at least 35-40 hours to recharge with your little charger. The CTEK's are good in that they can run in supply mode as well, which can be handy in some situations.
I'm beginning to doubt what I thought I knew

I'll check into that CTEK after work today. Maybe I can find it or an equivalent in town since shipping isn't an option right now.
Thanks!Comment

Are; your batteries new? Also, are they installed in your RV? If so, I am interested where they are stored and how they are vented.Comment

I don't want to touch what your trying to do with Solar because your trying to build a system without any principal of your needs based on capacity of the system.
A stand alone Battery charger used in a Off Grid system powered by a generator does not have to be a fancy smart charger. Generally your only doing a bulk charge to get you through to the next available PV input. You want a charger that can replace the amps hrs to get you to 80% of capacity or so and the PV does the rest. It's also nice to have a charger that the output voltage can be raised high enough to do a Equalization Charge ( EQ ). Usually the low end chargers have a terrible PF ( power factor ) but they have a honest output of their rated amps. That means when you run the generator your batteries will bulk charge faster with less fuel even with a bad PF. Smart Chargers with digital control can rarely deal with a inverter connected to the Battery bank and see their load as a fault and their output amp is not the rated size.
The charger from Amazon would probably be a better choice for down and dirty off grid charging. I don't know anything about it, you have to test it. Basically it a 2/10/40 amp charger, the 200 amps is a emergency starting function to start a car with a dead battery.
My choice is a IOTA power supply type charger. You can get them with the IQ4 option for control and get the rated output hour after hour.Comment

I see you are now aware you need a better charger. That is the one thing that will save your batteries until you get your solar fine-tuned. In fact, you will probably need it on a regular basis. I don't recall what your geographical location is, if it has been mentioned, but likely your solar insolation numbers won't be sufficient in the Winter. I have been told that in this sort of situation, use the generator/charger in the morning to bulk the batteries and then the solar to finish them off works well.

You may want to rethink leaving Saturday.

Wife and I are talking about delaying until Sunday and putting a few more miles between us and it (assuming the models hold true), but yeah, I'm pretty nervous about that to be honest.Comment

Looks like it's going to be running right along the side of me on the way up too. I'm coming from FL.

They are saying Maryland is in the bullseye specifically the Chesapeake bay which if it goes west we will have major flooding.
So glad I don't have a boat in the water any more.NABCEP certified Technical Sales Professional

I'm not far from you, SE. Just outside of Tampa around the Apollo Beach area. We had a really calm hurricane season, I gotta drive out of state in an RV (or the first time)... and BAM, following a hurricane all the way up. Good times.Comment

Just make sure your generator works and then you can at least park in a Walmart lot and "dry camp" with some comfort.Comment

Some of the videos being shown on the news show a lot of cars being flooded out in parking lots. Those cities have to clean out their storm drains every once in a while for that potential 4 inch per hour down pour.Comment

Yup. And just watch, when I get there, the field where I'm parking will be flooded too and I won't be able to get back in it. Shoot, my dirt road might be flooded, that just dawned on me. Unbelievable. What a way to start the off-grid lifestyle, huh? Head first into trials and tribulations. No honeymoon period for this family. LOLComment

I wish you luck and safe driving (and parking).Comment

You may wish you had a small john boat to get around if the tide comes in like it did in recently in some of the East Coast states.

I did have a Jon boat and spent the day ferrying folks from the upper parking lot (about 7 feet above normal high tide.) to their boats that had floated over top of the piers.
It was interesting to say the least.NABCEP certified Technical Sales Professional
