From a purely lay persons perspective and from some one who has been living off the grid for a good few years now, with lots of appliances and gadgets on board for everyday living, after reading all this technical stuff in this thread I think we will continue to stay with our KIS system. Is it just me or do a few people who are not electrically trained, find all this a load of mumbo jumbo?
Life is too short to bother with stuff that is so complicated! We have proved as many others have proved, living off grid in a well set up motorhome, with adequate power can be so simple, one has to ask why do the 'experts' out there make it sound like rocket science!
The 4 x 120 solar panels, 1 x 45 Morningstar MPPT solar controller, a votronic monitor, a Xantrex 1800i inverter and 2 x 260 amphr AGM batteries, this combination works so well for us. Living full time on the road in a motorhome, I need to be able to turn the inverter on and all my power points revert to 240 allowing me to plug in the toaster, the coffee machine, the hair dryer, the hair straightening tongs, the kitchen whizz, the slow cooker, the vacuum cleaner, a steam iron, and that is just for starters. Of course I know I cannot turn all the gadgets on at the same time but that is a small hardship for the privilege of being able to live this lifestyle.
We recently replaced our batteries because they were starting to show their age with the same as what we had for a few dollars over $1000.00. We read long and hard about Lithium but it was exactly what has been demonstrated in this thread that turned us against them plus the ridiculous cost here in NZ. We have been parked stationery at Ardmore for 6 days, alot of awful weather and grey skies up til today,
( we have both had this nasty cold bug that is doing the rounds) at 9.25am this morning our Votronic monitor showed the batteries back up to 520, the morningstar solar controller is green blinking and the other monitor shows that there is still a small amount if solar pulsing or trickling in, so from my basic understanding of a good power setup it is all doing exactly what it is meant to do!
Possibly when Lithium batteries and all the add-ons come down in price to a competitive level and when the suppliers realise that blinding the average person with science may be losing them sales rather than gaining them new customers, we may look at Lithium, but til that time I am glad we made the decision to stay with what we know and trust through our own personal experience.
