This must be the only product thats cheaper in Australia than the rest of the world!

Watch out for shading.. theres no better way to kill solar output than a shade line directly across a panel.

Choice of controller really depends on the panels you've chosen. If they have a high Vmp (likely for a 140W panel) then you'll be better served by a programmable MPPT controller like the Victrons. A PWM controller wastes the voltage between the panels Vmp and the battery voltage. So if the Vmp...

We have the standard 2.5 x 10 "twin" filter setup with a 20 micron strainer + 5 micron carbon filter outside treating all water, while the drinking tap is supplied by a separate tank plumbed with a seagull IV. We're currently looking at RO systems like http://www.h2oonthego.com.au because we...

Keep going, after you drive it out of the drive way on your first trip the sweat, tears, and long days are quickly forgotten :)

Lithium could be more cost effective for higher loads, what sort of loads are you running? eg. 100Ah Lithium has similar usable capacity to 200Ah AGM, but once you start drawing loads higher than C/10 (i.e. 20A on 200Ah AGM) Lithium provides more usable power. Lithium is also more suited to...

1. I like the blue sea MRBF fuses for this purpose as they're directly on the battery terminal. 3. No need for a fuse in the panel ->controller run , the cable the panel is supplied with will be able to handle a dead short. 4. You can't have too much solar :)

I prefer larger grid-connect panels in parallel as they're more efficient and will perform better over time than nominal 12v "RV" panels. Can you fit two 1.6m x 1m panels? For the portable panels i'd wire them in series to a MPPT controller like the Victron 75v/15A as this will help reduce...

Not sure how the security works on the remote... but if its a simple 433Mhz radio i'd be concerned by accidental operation?

That could be the 700, not 702. The ad is a bit vague.

I have no doubt the smartguage works as advertised, but is it worth almost double the price just to save installing a shunt? The other big issue is its not compatible with new battery technology like Lithium, so it becomes an expensive throw away item when it comes time to upgrade. With a...

This is a big benefit of MPPT controllers over PWM for RV use. We have 4 x 100W portable flexible panels that we put in series to produce almost 80v at just 4.5amps. I can use our standard 25 meter long AC extension lead (2.5mm2) to put the panels well out of the shade with less than 2% voltage...

Does the Trimetric do logging? The BMV has a bluetooth dongle available which talks to an IOS/Android app thats pretty neat - It can also talk to a PC via a ttl -> USB adaptor ($5 on eBay) or to the CCGX control panel and VRM as part of a more integrated power system - The Victron...

The Victron BMV-702 does voltage of the 2nd battery bank (or temperature / midpoint of the primary pack) All Victron gear also comes with a 5 year international warranty, peace of mind was one of the main reasons we went with Victron.

I'd probably look at a smaller inverter too, a 3000W inverter might waste between 20W and 50W just being turned on. We went the same way as Maninga with a LG PF1500 projector - 1080p and LED bulb so no problems with vibrations or having to wait for it to cool down. ~55in screen inside and...

This one. If you're planning on running large loads spend some time reading up on this pesky bloke called Peukert, he could steal another 5-50% depending on what type and size your battery bank is!

That one doesn't seem to support any wireless interfaces, only USB so you'd need another device for wireless "brains" The units I use have a reasonably standard "Xbee" socket so you can add Zigbee/Xbee, Bluetooth, WiFi or something else depending on what you wanted. The 4 channel 10A units are...

Another option to consider - a raising bed like ours that could be stopped "half way" allowing the lounges to be used as bunks? Our lounges are 2m long and 60cm wide, I'm often found snoozing on them :)

Interesting, how much insulation is up there? We only have a 35mm high density polyurethane roof and one day I left a packet of black cable ties up there in the sun... A few hours later our thermal camera had no problem spotting the offending cable ties from inside the truck! An air gap...

Those FX videos are neat, although i'm not sure about the solar one below them... mounting a flexible panel solar like that decreases the electrical output by ~15% and will increase the interior temperature dramatically!
