You should have been monitoring your batteries. Did you have a battery monitoring system? Did you check and add water to the batteries as needed over the 12 mo? Was the battery bank sized properly?
Ramblinrod - installing 100w solar panels is super simple, someone would have to work very, very hard to be able to destroy the boat, never mind destroying a marina. Killing people??

Every
marine electrical system is just waiting for someone to let the magic smoke out. AC or DC matters not.
Installing a
solar charging system (or performing brain surgery, or rocket science, or any activity for that matter) CORRECTLY is only simple for the people who really do know what they are doing.
About 10% of the folks who think they know what they are doing, actually do know what they are doing.
I have seen several
boats burned, marina docks and
fuel pumps damaged, and people hurt by incorrect
marine electrical wiring.
Of the marine
electrical systems I inspect, that have been modified by non-certified people, only about 10% are completed in compliance with marine standards, and at least 10% are patently unsafe (1 easily plausible condition, yet to be encountered, away from burning).
To put it in reality, 1 in 10 could catch fire any moment.
This is not an exaggeration; just because somebody has connected something to their boat, and it seems to work, does not necessarily constitute a correct and safe
installation. Not by a long shot.
Most non pro installations place the owner, crew,
family, and marina at unnecessary risk.
I know this because I inspect, consult, design, build, troubleshoot,
repair, and install marine electrical systems, professionally.
Ask any honest, association certified, marine
surveyor, how safe the average boat
electrical system is?
You'll be shocked. (Har)
And yet every DIYer insists their boat is safe.
I start out my marine electrical system seminars like this:
"1. Show of hands, how many boaters here perform their own boat electrical system
maintenance,
repairs, and new installations."
(Typically about 50% of the audience hands go up, but I know it is more like 90%.)
"2. Show of hands, How many believe the work they have done is safe?"
(Typically all the hands stay up.)
"3. Show of hands, How many will invite me to inspect you boat's electrical system, free of charge if no issue found, $200 if I find one issue that is unsafe and needlessly risks "critical to safety"
equipment failure or fire?"
(Typically all the hands go down).
4. Then I present all of the common
wiring deficiencies I encounter and what can happen as a result.
5. After the seminar, about 10% walk up, hand me $200 and schedule an appointment. Until now they didn't know their boat was unsafe.
There is likely another 80% of the audience who has an unsafe boat but is not willing to spend $200 to find out.
That's right, not willing to spend $200 to help ensure their boat won't burn to the waterline tomorrow and possibly kill someone.
I would lose my shirt on these inspections, which generally consume about $500 in billable hours each, if I didn't make it back on the
repairs I'm hired to perform following.
To date, the best report I have prepared had 3 faults, each of which could result in fire, explosion or electrocution. 2 were related to the AC system and 1 to the DC system.
In summary, one doesn't know what they don't know until they do and approximately 90% of boaters are in a state of blissful ignorance that their boat electrical system is safe and reliable.
I recommend:
1. Every boater learn as much as they can about their electrical system and be capable of performing
emergency repairs.
2. After doing so, have these repairs inspected by a marine electrical professional at the earliest convenience.
As part of our "Boating Community
Service Program", if I'm walking through a yard on other business, and someone asks me to look at something, 15 minutes is free.
If I can't ascertain it is safe and reliable within 15 minutes (which usually means it isn't), I recommend a thorough electrical system
inspection (at my normal hourly rate). If they decline, they only have themselves to blame.
