[RE-wrenches] 60 Cell & Small 12 V System

[Daniel Young]

Hey Drake,

 

We're finding that the small systems are cheaper if you use a 72 cell
module, then a simple PWM charge controller with 24v battery and the
smallest 24v inverter you can find, samlex makes a 300w 24v sine wave
inverter for about $160. That combo can often come in lower than using a
special mppt charge controller just to deal with "bucking down" the voltage
for a 12v setup. It all depends on the details though. If they're set up to
run off of 12vdc direct, then adding an inverter is an extra expense, but it
can still work out. You just might want to price it both ways to see what
works for you with the pricing and products you have available.

 

With Regards,

Hello Wrenches,

A small town wants to put a kiosk in a park with a video display. It would
be great to power this with a 60 cell, 255 W module and charge a 12 V
battery. Morningstar has a product that would do this, but it will only pass
through 200 W. 

Is there a new product on the market that would be economical and not limit
the module output?

Thanks,

Drake
