I have a question please help! I just bought the complete 45 watt solar kit from harbor Freight http://www.harborfreight.com/cpi/cta...emnumber=90599 , plus also I got an inverter http://www.harborfreight.com/cpi/cta...emnumber=66817 . Can I add more solar panel let say up to 200 watt and adding two 12 volts battery using the same charges controller and power inverter?
adding more panel & battery

gee wizz...somebodies inpatient.
You can wire solar panels in parallel (i.e. positive to positive, negative to negative). Preferably, the panels should be similar to allow the output voltages to track. Otherwise, it may be necessary to include diodes in series with each panel so voltage variations do not have an adverse effect.
The other alternative is to have the panels charging individual batteries and then combining the batteries through diodes before using the inverter. This approach would require separate charge controllers for each battery. Not quite as energy efficient as each diode causes a voltage drop (and so a power loss).Last edited by Bruce; 10-06-2009, 12:01 AM.Comment

This is a forum, not a customer service helpdesk.
You have a 750w inverter there, so you can push that amount of power through the inverter. I would suggest getting one of those watt meters so you can see how much power something is using, hooked up to that inverter.
But yes, you can add more solar panels and batteries. Your inverter converts the DC power to AC, and your limit as per the size of your inverter is the wattage that you can pull out of that inverter.Comment
