[QUOTE="condor22, post: 513261, member: 1932"] You are correct re 290W @ 12V. the 100/20A is a 20 amp charger. If you put 40A into it, it will still only charge at 20 amps :). However, on days where panel output per panel is down, you may only get 5 amps charge, the extra panels will still bring up the output to nearer or to max. The Q is how much extra can the 100/20 absorb safely. [/QUOTE]
