Normal lead acid batteries are not happy with charging or discharging at more than 20% their C rating. Your batt bank is rated at 230Ah x 2 = 460Ah @ 12v. Your max realistic charge rate for your battery bank would be 20% of 460a = 92a. Your multi has a max charge rate of 80a, within battery specs.
A deep-cycle lead acid battery should be able to maintain a cycle life of more than 1,000 even at DOD over 50%. Figure: Relationship between battery capacity, depth of discharge and cycle life for a shallow-cycle battery. In addition to the DOD, the charging regime also plays an important part in determining battery lifetime.
From a great site for battery knowledge: Lead acid batteries should be charged in three stages, which are constant-current charge, topping charge and float charge.
Lead acid batteries typically have coloumbic efficiencies of 85% and energy efficiencies in the order of 70%. Depending on which one of the above problems is of most concern for a particular application, appropriate modifications to the basic battery configuration improve battery performance.
d acid battery can be written as:DischargeDuring the discharge portion of the reaction, lead dioxide (PbO2) is converted into lead sulfate (PbSO4) at the positive plate. At the negative plate sponge lea (Pb) is converted to lead sulfate (PbSO4). This causes the sulfuric acid n when a battery is being dischargedChargeDuring the recharge p
The production and escape of hydrogen and oxygen gas from a battery cause water loss and water must be regularly replaced in lead acid batteries. Other components of a battery system do not require maintenance as regularly, so water loss can be a significant problem. If the system is in a remote location, checking water loss can add to costs.
However, due to the corrosive nature the elecrolyte, all batteries to some extent introduce an additional maintenance component into a PV system. Lead acid batteries typically have coloumbic efficiencies of 85% and energy efficiencies in the order of 70%.

I''ve read that lead acid battery not should be discharged too quickly, as this might result in overheating the battery (and cause damage to it). How do I figure out what a safe maximum discharge rate is for a 12V lead acid …
The lead acid battery uses the constant current constant voltage (CCCV) charge method. A regulated current raises the terminal voltage until the upper charge voltage limit is reached, at which point the current drops due to saturation. The charge time is 12–16 hours and up to 36–48 hours for large stationary batteries. With higher charge ...
Lead acid batteries are best on low rate discharge. Most these days are rated at 20hrs. That battery is rated 8Ah, so will deliver that capacity when discharged over a 20hr period, at 400mA. At higher currents, the …

Lead acid batteries should be charged in three stages, which are 1 constant-current charge, 2 topping charge and [3] float charge. The constant-current charge applies the bulk of the charge and takes up roughly half of the required charge time; the topping charge continues at a lower charge current and provides saturation, and the float charge ...
