Hi all:
I have a trip coming up in three weeks and want to do some upgrades to my electrical system. I presently have a 9kw generator, a 20 amp charger and two, I think start 8D's for a house bank. This was adequate for the previous owner whom used the boat locally but not for a 3,400 mile trip.
First off I want to install a inverter/charger so I can run the 120v refrigerator and 120v freezer (both under counter) while underway. The other possible electrical loads underway would be a 900 watt 120v microwave, a 600 watt 120vcoffee maker, bilge pumps, lights and electronics.
My thoughts are 2,000-2,800 watts AC.
The current alternators are two 40 amp large frame on Detroit 4-53's
Port charges house and Starboard charges starting batteries. The generator has an alternator but charges nothing. The regulators are old.
One of the two year old house batteries has a weak cell that prevents the charger from shutting down and I do that manually. That battery has to come out leaving one 8D wet cell for starting and one 8D wet cell for house. My thoughts are to use the wet cell for starting and add LiPO4 bank. I am well versed in Lithium technologies and have built batteries before so not opposed to individual cells. Room is not really an issue on batteries at this point there are 3 8D battery boxes on the port side and nothing but ballast on the starboard side. I think I will need at minimum one more 8D but that seems dumb and still inadequate One of the current 8 D's is new.
More likely I would need an inverter/charger, a new voltage regulator for one alternator and 400 Whr lithium bank. At present I only have about $3,000 I can spend on it over the next week and more in a couple months
I have seen brands bandied about here in the electrical forum and it seems like asking for the right anchor but ask I will.
I am capable of hooking everything up according to ABYS but I am fairly ignorant of what's out there in the price range and obtainable within time frame I have.
I plan on adding more capacity within 6 months but limited right now. Asking for some solid advice.
I will still run the generator for cooking, AC and hot water.
