[MarinTeams] Channel 7 Repeater power outage restored

[George Shea]

At this time, in order to analyze the issue would be to determine how many amp hours are needed to keep the repeaters going given the kinds of transmission outages likely to occur. How many amps does the current repeater draw? In use or in standbye? Then, a decision for a generator/inverter that is either autostart or internet start might be considered is the money is there. Solar is also being used quite well. Show me the money.
Otherwise, end of discussion buy new batteries, I hope lithium.
I am replacing my "house" batteries on my sailboat with lithium bought through home depot.

 Charging would be done either through a generator auto start, which they do make.
Or a C, which is the problem as it goes out then what?
It’s nice having multiple systems so you have a little bit more of a failsafe set up
Question, depends on how important the scenario is so you know how much money to throw at the solution

LFPs are lighter, they deep cycle, most have internal controllers to avoid over/under charging, can get at least 4,000 recycles, NO MAINTENANCE, still work fine way past the 50% discharge limitation all other batteries etc. A little expensive, but getting cheaper, especially if stored inside. Maintenance free other than charging, and easily convert to solar when available.
I suggest solar unneeded if reliable source of power to charger keeping batteries topped up.

 Agreed and there’s some maintenance on them too.
At this point other than the expense, LFP batteries are so much better of a long-term solution.

AGMS that are recycled many times (as in solar installations) easily die after four years especially in cold weather.

 We have four AGM batteries at the site in West Marin.  It has been solar powered from the beginning and has been running uninterrupted for 4 years, I believe.  Will have to check, can't count that high..

That’s tough with all the gray weather we’ve had two you’re talking about a lot of batteries. It’s the storage that makes all the systems work.
