MusicTank Mk. III

Step 2 Designing the Batter Well

after field testing the Mk.II; we kept hitting a roadblock with our battery. The system was running on a 12v 18ah battery supporting a load that was 50 watts+ per hour and the solar panel that was supporting the system only pumped 5 watts per hour back into the Battery Well.  This only allowed for about 5 or 6 hours Max playing music from the amplifier... 

We need MORE POWER ! !

The new Battery Well solves this, by wiring similar 12v batteries in parallel we combine the number of Amps, this creates a deep well of potential electric power.  By deepening the amount of potential energy, we multiply the length of time the system can be used.  With a combination of a deeper Battery Well and a Panel that outputs at a higher wattage we will have a Self Sustaining System .  


I added a 40 amp 12v battery that was 8" wide 6 1/2" long and 7 " tall
fitting it perfectly under the suspended charge controller.
The new battery will be the primary battery in the battery well (battery bank), it will be wired first in the bank and will get the most use for this reason. the batteries will be interconnected with no less than 8 AWG wire cut to fit with 8 AWG ring terminals connecting to the battery terminals.   I found a battery that fits perfectly well but before you secure it to the structure you must wire and place the ON / OFF switch and other wiring.
