Solar Panels 6 Sanyo 190 watt 55 VDC panels, connected in pairs. ~11.4 kwh (kilowattt hours) daily total (10-hour summer day) on custom tilting rack
Combiner box Outback FWPV6 Combiner Box: 3 dc circuit breakers combine power from 3 pairs of panels
DC wiring between combiner box is #4 stranded insulated copper cable
Charge Controller : smart control of battery charging
Battery 42 LI-ion battery modules (each containing 8 internal cells) recycled from a Nissan Leaf.
A 2012 Nissan leaf had 48 of these modules, so the trailer has 87.5% of that capacity.
The Leaf was rated at 24 kwh (kilowatt hours) of energy storage, so that trailer has approximately 21 kwh (actual performance will probably be a bit less).
Each module is 8 volts fully charged (Capacity: 41Ah Maximum Continuous Charge & Discharge Current: 130A)
6 batteries are connected in parallel to create one bank. That's still 8 volts Connections are made with bolted copper bus strips, 1.5 wide, 1/4" thick
7 of those packs are connected in series. That's ~ 48 volts (56, sure, but this system runs at 48 VDC)
(note: our Leaf batteries are from first generation Leafs (2011-2015)
Inverter : creates household-type 110 Volt AC power
DC wiring between battery and inverter is #4 or larger stranded insulated copper cable.
Cut Off Box Fused master switch for one touch diconnection of all AC external power
Service Box Standard household-style service box which distributes AC to 6 external household-type weatherproof AC outlets on the outside of the trailer.
Each outlet has its own 20 amp switchable circuit breaker. The breakers are
All AC wiring between inverter and service box is #6 stranded copper wire, rated for 60 amps continuous use.
Each outlet is wired with #12 single strand insulated copper wire, rated for 20 amps continuous use
AC outlets 6 external household-type weatherproof AC outlets on the outside of the trailer. Each outlet is its own 20 amp switchable circuit breaker.
Trailer rental includes all the 3 conductor grounded extension cords you'll need.
Information & Monitoring Systems
These communicate with the Flexmax Charge Controller & the VFXR Inverter to control, monitor, optimize, and report panel and battery performance.
