Re: Batteries again

I had a sailboat that was hull #50 from the company. They were obviously just getting started and didn't have the manufacturing infrastructure, so the fiberglass hull way laid up by hand. The result was a nearly indestructible hull, especially compared to the later issues that were made using blow m...

Re: Recommend a backup generator

I have my local generator mechanic do everything but oil changes on my EU7000is, and the only time i could imagine he'd do valve adjustment is annual maintenance. I've never heard him say anything about the valves needing adjusting but he may have. Other than that, no guidance about it needing to be...

It was not a correction. You are correct. 350Ah was listed in the manual as the minimum for Radian, but there there was an additional info that it can be as low as 200Ah for "systems intended to bridge short term outages".
I'd imagine 200Ah would be a stout, but short bridge.

Re: Batteries again

I'd like to know if there could be a problem with system compatibility, a bad batch from the factory or if operator error played a part. I'd settle for educated guesses.

Re: Off Grid upgrade

Seems so Consider - any system only has 3 shunts at most. My current system has 4 inverters, 4 CC, how could you logically split other than all inverters on one, all CC on one. I think other systems use the 3rd for either other inputs or loads. That's how I'd do it. The 3rd shunt could be used to s...

I’m getting the prewired units. Have to add the 4th CC. Not sure I see any advantage to CC being on own shunt. The info is available on the FM itself. Hopefully that would mean C would be available.

Re: How can I get generator to only power charger?

Re: Adding an additional charger

The 3648 can output 45DC Amps continuous for charging, X4 that's 180DCA. Will your battery accept more than 180DCA during Bulk charging? If so, and neglecting any contribution from PV harvest, the generator could be equipped with an external charger to add additional current. The external charger wo...

Re: Absorb charge worth the cost?

A lead-acid battery below full charge will have a lower electrolyte specific gravity. The sulphur not formed into sulphuric acid will end up coating the lead plates as lead sulphate, or precipitate to the bottom of the container. Chronic undercharging makes these precipitates more permanent, resulti...

Re: Newbie Needs Help

My apologies for making it sound like an engineering exercise. I edited for, hopefully, clarity. The input current setting is to let the inverter know what to expect in power capability from the generator. The number is expressed as AC Amps. If the AC load is going to draw more Amps than the number ...

Re: Newbie Needs Help

A 10kW solar array could certainly feed a good deal of charging current at full output, perhaps as much as 200A, so it's not surprising under certain conditions, the battery would charge fairly quickly. The Radian GS8048 is capable of 115A continuous charging current, so will charge at a decent rate...
