I was wondering if anyone could comment on why I should or should not build this (see attached diagram)... it's a step up (or perhaps down) from how I've used my solar array and existing battery bank in the past, which was basically just feeding power directly from my solar array (currently about 33w) into my battery bank (was using 8xparallel 12v 2ah SLA) and connecting my inverters/regulators off that positive rail no current or voltage regulation. The solar array was connected previously via a over-voltage cutoff device which read the voltage level of the batteries. The relay which connects the solar cells to the battery bank is intended to perform a similar duty in this (currently theoretical) circuit.
I did some work last summer experimenting with the max4172 ic's which appear to offer reliable readings as to how much current is flowing between given points in a circuit.
Any suggestions on how to improve this circuit without adding a lot of complexity?
Any comments regarding the use of diode's in the circuit to direct traffic? The intent was to prevent power from coming into the batteries aside from what is flowing through the voltage / current regulated source while still providing any additional power coming in from the solar array directly to the regulators which provide power to the connected loads.
