It makes me very nervous for you using a very complicated piece of machinery in a salt water environment. I'm sure the Bluetti was not designed for marine use (hell, even many "marine use" electronics aren't ready for prime time on the water), even if they pseudo-endorse marine use by giving you a freebie. Moreover, your voyage is going to have long periods of soaking wet, inside and outside the boat, that would probably fry even most so-called marine electronics. For example, if that complicated cable connector gets corroded, or has a piece of gear hit it and breaks off, there goes the whole unit. I'm glad at least that you consider it a backup unit, though it still is one monstruously large "single point of failure" you're building into the boat. My brother is a former commercial offshore shrimp fisherman and now a pilot boat skipper, and he has all kinds of stories of woe about "professionally installed", "marine use" gear that not only fails, but fails when under stress, when it's most needed, so he advocates all mechanical gauges and sensors, analog devices over computers whenever possible, and always have 2 backup plans, e.g. automatic bilge pump backed up by hand operated pump, backed up by a bucket and a strong back. I know you have tons of experience on the water on heavy and long offshore passages, so you know what you're doing, but just saying'.

Energy capacity is expressed in watthours. Power capacity is expressed in watts. Always talk about watthours with battery capacity! Power x time equals energy, hence (watts) x (hours) = watthours of a battery. That 3000 Wh battery can run a 300 watt load for ten hours because 300 W x 10 h = 3000 Wh. I think a small to medium sized refrigerator consumes roughly speaking 1 kWh (one thousand watthours) over 24 hours, so one of those things will keep the milk fresh for three days of blackout – if nothing else was using up its energy.

Reliable portable modular systems are coming of age finally. Your review of the Bluetti AC500 reflects a well thought out design. It is a very viable system for eliminating the need for a generator especially for infrequent power outages.

ONE QUESTION:
• Can the Bluetti AC50 also be tied into your home main electrical panel?
If so, this would make life even easier for Mrs. Rover.

-----

MY HOME:
For our home we started out with a 5000 watt (7000 watt surge) generator first with.a generator switching panel then with a whole-house connection that needed manual attention when switching. NOT ideal for the non-technical. Since this was a pull start and my wife does not have the upper body strength to properly pull the starting cord, we upgraded to a 8000 watt (10,000 watt surge). With this generator we can run the full house including the electric dryer!

In March 2015 we added 8.2 kW-hour solar array on the roof — 30 panels with Enphase microconverters almost perfectly covered the roof. The grid tied system meets all of our needs with a slight excess over the year. We pay $18 per month for the power utility connection charge.

ADVANTAGE:
Since the system is paid off, the recent electrical price increases had no effect on us.

DISADVANTAGE:
• Grid tied systems shut down when the utility lines go down (to protect from back-feeding into downed wires.
• Snow on the fixed roof panels needs to melt enough to "slide off" much like metal roofs. (My nephews use post mounted arrays that they rotate the panels to vertical.)

We recently purchased the Enphase 10 kW-hr battery storage with a "smart switch" that will disconnect from the Utility line while directing the battery power to the house main panel in milliseconds. Very important for home medical equipment.

MY BOAT(S)
My Capri 22 has a 160 W solar panel for the house battery AND motive battery. It has a Torpedo Cruise 2.0 ideal sized for it. Other than experiments with various chargers and battery chemistries, I have reliably used this setup for the past decade.

My Catalina 310 will have 2 solar panels totaling 850 watts. The house battery and galley demands are much greater that my wife expects she needs. (I on the other hand, hope to replace the noisy diesel with an electric drive.)

With my boats, sailing is the primary propulsion. The auxiliary motor is just that – an auxiliary, to be used in mooring or docking, occasionally for windless conditions. We love the quiet of an electric drive.

Thanks for the very interesting video. Inverters have come a long way with modern technology. Always good to have an efficient back up system. What is the weight of the Bluetti unit you're going to use on Wave Rover?

What a great system! I'm going to check out this system for our home use when the powered goes out here in the country. A few years back we were without power in a 36 inch snow fall for a week….this would have been a game changer.

Well you just lost this subscriber, if I wanted to watch commercials I wouldn’t be on you tube. I enjoyed this channel when it was about sailing and boat building but the begging needs to end. It really makes you look pathetic and lazy! 23 minutes, really?

Alan have you tried this unit to run your well pump?

You are looking a lot thinner Alan!
