So you'd need an inverter and that's really inefficient, put the money towards a compressor fridge instead
I am now of the view you can get the bets deals by buying the bits separately. The Photonic Universe flexible panel I have got is available in bigger outputs for not that much and good MPPT controllers are maybe £65. £200 will get you a quality setup
Nope, I think 4amp is a good figure for 100w so you'd probably be in deficit @pkrboo @theBusmonkey will know more
I think in the real world none of the panels would keep up with what you're using on a minute by minute case but would slow down how much you're depleting the leisure battery. Then when your outside the van having a drink or going for a walk or off down the pub for a meal your fridge won't get opened so it won't have to work so hard, no lights on, no stereo etc and the solar panels will gradually refill the battery.
But your fridge pulls 8a for 24hr and at best your solar puts 4a in for 12? I'm just guessing mind.... I think solar will extend a fully charged battery's span of use but to totally rely on solar would need a fair few watts
With split charge and the odd day on hook up I think solar is a great addition though, not something I can see us needing though.
But a fridge doesn't work 24 hours a day, it's only using electricity when the motors actually running. Obviously that's more during the summer but even in summer I'd be surprised if it was running for more that a third of the time. I've got 200 watts and I'll be dissapointed if I need a hookup all summer.
The waeco compressor cool box that I have pulls 5a I think but the duty cycle is 15% so average about 0.75a/hr. A decent solar set up should keep that going indefinitely Sent from my Nexus 6P using Tapatalk
First outing with it this weekend so I will let you know! I'm hoping to get 3 days in the summer with led lights, fridge and phone charging. Probably less this weekend as the propex will be in use. Very tempted to stick a 100w panel on then I should be self sufficient Sent from my Nexus 6P using Tapatalk
Oh if you mean solar during the day and then battery at night I think that would be easily achievable. 12 hours would only use around 9 amps, maybe less as it's generally colder Sent from my Nexus 6P using Tapatalk
