"A battery charge controller incorporates an MPPT to optimize charging of the batteries. Assume the maximum power voltage of a PV array to be 99 V and the bulk charge voltage level of a 48 V vented lead-acid battery bank to be 56 V. If the conversion efficiency of the MPPT is 98%, estimate the percentage increase in charge delivered to the battery under these conditions over that which would be delivered by a controller that causes the array to operate at 56 V rather than 96 V. You may assume the PV array consists of three modules connected in series, that \( V_{mpp} \) is independent of irradiance levels, and each module has \( V_{oc} = 42 V \), \( I_{sc} = 6.25 A \), \( V_{mpp} = 33 V \), and \( I_{mpp} = 5.76 A \)."
