  1. So I have a 100w Renogy solar panel and a 1100 w inverter and a group 27M RC Minutes 180 battery. I can't run a 900w coffee maker off this it kicks off as soon as I plug in in, what else do I need to make this work?

  2. Hi Matt, very interesting, thank you for the info. Can I ask you, what Wattage would you recommend for a 6 berth camper motor home, 2 people touring Southern Europe, Med coast for 6 months ? Will not have access to mains power most of the time and would like to use a toaster, boil a kettle, charge a mobile phone, lap top ,cabin lights and a fan. Estimated daily sun hours, 8/9 or more. Appreciate your advice.

  3. I have a 12v dc water pump that will be running 24/7 to circulate water. it doesn't have any Amps written on it. just says 12v. how would no work out how many watts it uses per hour?
