Pete, do you propose using a hydrometer everytime you want to know your
state of charge? This could be a couple of times each day, or more.

Hi,

For those who know a bit about electrics and can use a hydrometer I
would propose:

Do an energy budget/audit.

Size the battery bank for 40% DoD (depth of discharge) on a normal
days/period of use

Use the hydro to verify the above a few times as well as check the
batts are getting fully charged.

Use the hydro to check a few times that an exceptional days/period of
demand doesn't draw the batts below 80% DoD

Comments???

cheers,
Pete.
