Update, after talking to Tesla about the change from 272 to 265 when 100% charged they told me the battery will withhold a little room ( but show 100%) based on our driving habits ie: if we use a lot of regen braking historically, the car will allow for that and leave room for that regen power...

every day for the last 8 years , but I do my best to keep. them above 50% SOC. they're the sole source of power for our home

at 5 months? I have LFP batteries powering my whole house. they don't degrade that fast

Aloha, Our '22 M3 started out with 272 miles at 100% SOC. then it went to 267 at 100%, now 265. car is 5 months old and temperature isn't an issue here in Hawaii. we were told to charge to 100% at least once a week with the LFP. Any ideas why the range at 100% is dropping? Mahalo

It worked! mahalo for the tip

we've had our M3 about a week. connectivity was fine until yesterday . Car will connect bluetooth when in the car, but not remotely through the app. It's got the latest software. What is a "soft reset". Some are saying that will fix the issue, Mahalo!

circuit installed( GFCIs etc) very happy to report I'm getting 21 miles of range per hour of charge at 20 amps. This is better than I had hoped for. If it gets cloudy I just drop the amps accordingly. Because of the intense sun here in Hawaii my home batteries are full as of 9:30am so I can...

listen I really appreciate everyone's input. My electrician has dome multiple "off grid" Tesla hookups here on the big island. Living solar/battery has challenges and I've learned to be careful. In 10 years he hasn't steered me wrong . If I later upgrade with more batteries I won't need to...

I'm going with the 14-50 socket. after talking to tech people at Tesla, they just advised to manually set the charge rate ( and check to make sure it's the same before each charging session). 14-50 adapter ordered and shipped. Hope the car has a cable when it arrives ( ordered feb10, supposed...

I will definatl I appreciate this, and will definitely ask the electrician about this!

pS, the charging cable she's lending me has the 5'15plug, but that's not going to show me what my system is capable of ( I will try it but 3mph won't work. the distances here on Hawaii island are far. Mahalo for your input!! Mahalo Ray, I am planning g to manually adjust the charging rate on...

My electrician says the system is capable of 25 amps ( it's a 48v 6.1kw offered system feeding 4 Simpliphi 48v batteries). I think that's why he said the limit for the Tesla should be set at 20 amps. a friend is lending me her M3 while out of town so I plan to test it, but the electrician is...

It's the max drawing from the batteries. I won't be trying to charge at night as the batteries will drain too far

Aloha, I'm offgrid 6.1 KW array capable of 25 amps max. 3 questions: I'm having a Nema14-50 outlet installed, will the cable that comes with model 3 connect to that? the other question is that I'm being told I must limit the draw on my system to 20 amps max. can you set the model 3 to only draw...

Mahalo!

Aloha Randy, Sorry if my questions are stupid. I think this might be the answer to charging our soon to be delivered model 3. We are off grid solar in Hawaii, 6.1kw(max) possible 24amps(max) . Concern is the Tesla stopping charge when refrigerator or some appliance kicks on. if this solutions...

Wife's commute is 80 mi round trip ( Big Island is larger than Connecticut 2400+ square miles!)

Aloha, I'm very interested in your solution. I'm trying to figure out how to manage a fluctuating solar output ( we're off-grid) . The model 3 wi;; be fine when system is at it's peak ( 6kw 24amps, 240v outlet) but afraid car will have a "fault " when a cloud passes over etc. Car id supposedly...

Mahalo! I will look into this!

yes, I have the optics RE app so I can see the readout of the Mate3 from anywhere. ( shows battery SOC, solar production etc)

fantastic, I think the 4 LFP batteries are capable of being that buffer if solar production dips. I'm getting great input on this thread ! The idea is to charge as much as possible here, then the wife can charge it on L2 charger at work ( no Tesla chargers on the big island :(

Mahalo! yes I need to find a software based "smart charger" that adjusts based on what's available. The system is 6.1kw 48v ( 4xsimpliphi LFP batteries) 2 outback inverters ( master and slave that kicks in for higher loads) 2 flex80 charge controllers.

Mahalo! would the M3 automatically start charging again once the voltage/amps return? ( It will be a pain to have to manually restart the process every time a cloud passes over)

Aloha, We have a M3 on order. We're off grid ( 6.1kw, 48v capable of 24amps, installing 240 circuit)) we know we cant charge at night. our batteries are full at 10 am and have 10-4 pm of solar charging available. My question is, will the model 3 adjust the charge rate as voltage fluctuates (...
