For $1500?? Wow, that would be a very reasonable price from other offerings I saw.
I’ll post the details here when it all pans out….
^^^ This is what I would do.
Could be because of the SR battery models design with one SR battery and one charger - the ER adds a second battery "pack" and a second charger.
Yes.
Interesting what’s happening, I followed your suggestion to charge the truck while still topping up my house batteries and obviously running the house load. The truck immediately drew its max of 9.6kw as shown on the app. The house battery charging dropped that same amount and everything in the house is still running as normal. I have a bit of haze today so I’m only getting 33kw in from the sun. My system obviously prioritizes the house load (including the truck) over charging my house batteries,
For the occasional case where you wouldn't have enough solar to run the house loads and the charger at the same time, you'll probably find your house batteries would kick in and make up the difference. In those cases, your house batteries may run a deficit for a while. That would be a watch item on cloudy days. A setup like my Emporia EVSE would simply stop charging the truck or reduce the charge rate if there isn't enough solar to go around. You would be able to set it up to prioritize house loads first, then either house batteries or EV charging as you see fit.
Well that would be my other house...it's in the tropics and the trade winds blow pretty much all the time - a rare day when there is no wind. And my house is near the top of a hill (Lat and Long: 16.7471N, 62.22605W, elevation: 328 ft above sea level).
WOW Montserrat?Well that would be my other house...it's in the tropics and the trade winds blow pretty much all the time - a rare day when there is no wind. And my house is near the top of a hill (Lat and Long: 16.7471N, 62.22605W, elevation: 328 ft above sea level).
I barely use 10kWh per day there, mostly for ceiling fans and the big draw is the refrigerator, sometimes run the washing machine once a week or so - the sun and wind dry the clothes, have a gas range, LED lights, not much used by the TV and stereo.
A small turbine VAWT (vertical axis) is what I am considering.
But actually there ARE turbines designed for low speed wind - whether they are worth it depends a lot on your energy storage capabilities and energy needs.
I haven't kept track of the wind speed at my house. Next visit I'll see what I can determine.
But there is a pair of commercial wind turbines up on an adjacent hill (St Georges Hill) that were operational producing about 200kW before the volcano became active again beginning in 1995 and then had a major catastrophic event in 1997. They are too close to the volcano dome now to be repaired and made operational.
There is no grid-tie available yet - they keep talking about implementing that but things move slow on "island time."
That is one thing holding me back from installing solar and wind there, that and the costs of shipping and import duties. Then there is the risk the volcano will get active again - been quiet since 2010, at the surface anyway. Below ground, still growling.
Volcanic ash is very acidic, producing acid rain that is good at dissolving metal quickly. And it is heavy. That is one thing to consider if I put solar panel on my roof - I have a lot of south facing yard I could utilize instead which would make cleaning ash off panels easier.
Then there is the possibility of a hurricane - Hurricane Hugo was a direct hit at cat 4 or 5 and shut down Air Studios Montserrat for good in 1989.
Always something..
Do you have a place to go when the Volcano blows.?????
Oh, ok, ...so they both have an HV battery arrangement with 9 modules, but some modules, apparently 8, have more cells in the ER.
Thanks.
