Battery storage with solar
I was reading in Trojan’s literature that to properly store lead acid batteries It is best to monitor voltage or specific gravity and recharge batteries when they drop to 70% charge (12.37 volts). I ...

I was taught how the constant solar charge is not enough amps. The flooded batteries like that big beefy charge. Also the solar controller might not reach high enough voltage. I always forget. Don't we want 14.7 or 14.8? Your controller might allow you to choose a flooded option.
Modern MPPT solar controllers will provide plenty of amps and volts to charge flooded batteries, if the solar array is sized appropriately for the battery bank.
An occasional top off with a AC powered multi-step charger is still a good idea.
