Background:
While on my 20+day US
Route-26 End-2-End Adventure ran out of Group-24 Battery power on a
five day dry camping run { in a campgrounds but no services }.
Suspect had the Fridge on 12VDC while stopped plus TV might not be
charging with Fridge on as well as thought now that battery is two
years old. Anyway, on the second morning Adle would not stay on (and it was Cold) . .
. no warning messages but did notice the Battery Voltage was low. On
third morning plugged in TV and Adle ran fine. Of course a couple
hours of idling the TV would not charge a battery.
Decided during my Oct-Dec
down time to get a Generator and increased Solar wattage. T@B now
has a 10W panel that has worked very well as a tickle charger between
trips. No way 10W will charge a low battery, less so with limited
September sun at my camp sites.
Solution:
For ~$400 (with huge WA
state tax included) have purchased a new iPower 1600W (2000W peak)
inverter style gas powered generator. While I've not been able to
test with the A/C Compressor running its ratings are well above what
a 5,000 BTU A/C and 5Amp Convertor/Charger will need.
Next built a 150W Solar
Suitcase. Since I already have one solar panel and a basic PWM
Controller all of the 'packaged' suitcase options seemed too
pricey for the wattage + included a controller I did not need &
had short cables so additional funds would be needed to make it more
'get out of the shade' compatible.
My suitcase will provide
150W at less than $300 cost. Actually, $240 as $60+ is for a nylon carry
case. May return that case . . . have an idea for a DIY case made
out of heavy plastic sheeting taking space in the garage. Am using a 20-foot SAE 12AWG cable for connection.
