[QUOTE="condor22, post: 589117, member: 1932"] Gravity, 1. If you are charging from a 120 W solar blanket, you max output will be around 7.0 amps, so you don't need a 30 A controller. 2. The one you link to is PWM, you will get 10-25% more out of an MPPT. 3. The profiles in the 30 A still hit a Lithium at up to 14.4 volts. 4. The 40 A mains charger hits a Lithium profile at 14.6 V. Be aware that if you use all or most of 1000W from an inverter, you can draw up to 100 amps from a battery. Most of what I need 240 VAC for I can get from a 150W inverter, anything higher, I crank up the genny lol. :) The easy calculation to know what amps a battery provides to an inverter is to divide the W by 10 not 12 as there is an efficiency loss. i.e. My first van was fitted with a 300W inverter so 300 / 12 = 25 amps. But I know from measurement that it used 27.5 amps = a 10% loss. [/QUOTE]
