FAQ Suggestions

Stella work bud!
 
Appreciated guys. There's more updates coming :) Just might be a little slow now that florida "winter" is here this week :p
 
Hahaha, no, just 35F lows for the next 4 nights :p
 
One question I see again and again (and have gotten tired of answering) is why use lithium-ion instead of lead-acid. This must come up at least once a week on facebook.
 
There are no definite answer to the LA vs Li question. It depends on the user and scenario. its like BMW vs Mercedes.

We can describe them but we cannot tell users if either or is better as a general answer.
 
There are good reasons for and against lead acid batteries. I don't think this is suitable for the FAQ. The question implies that you should choose lithium over lead acid, I think this is the wrong approach. You shouldn't do that. You should choose whatever is better suited for the given situation.

If we put something like this into the FAQ then it has to be rephrased, like "What's the difference between lithium and lead acid batteries?".
 
I think the hard part is explaining that not all batteries are the same, and Li-ion is fundamentally different from the chemical batteries we've been using for the past 120 years. Comparing stats, lead acid is only superior in three; initial cost (vs new lithium cells), cold weather performance, and overall system complexity. When you take into account that most of us are re-purposing used cells at very low cost, lead acid looks even less appealing.
 
To be honest, when reading this I get the feeling that you might be misjudging the situation and underestimating the value of lead acid batteries, even by year 2019 standards.

But still, make your suggestion. If you think that you have something valuable to add to the FAQ then put something together and we will talk about it. Don't be disappointed though if it doesn't make it into the FAQ in the end.
 
I'm on my way to pick up 400kg of lead :p
 
We wont add any conclusion or suggestions that states One is better than the other. We can add data and info om whats what and then its Up to the user to decide. Because even today both have its areas :)

Feel free to come up with content for it
 
Hello!

Can the following correction be made to the section "Inverters: What size inverter should I get?"
located at "https://secondlifestorage.com/t-Inverters-What-size-inverter-should-I-get" :

At the end of the post, there is a link to "Current monitoring with non-invasive sensor and arduino" that currently points to a non existing page at :
http://homautomation.org/2013/09/17/current-monitoring-with-non-invasive-sensor-and-arduino/

The correct link is:
https://homautomation.org/2013/09/12/current-monitoring-with-non-invasive-sensor-and-arduino/


Cheers!
 
Thanks for the update. Looks like the moved the link on their end. The only difference in the link is the day posting. Not sure why they moved it. Ohwell, thanks for the heads up. It's fixed now :)

It may also be worth adding that some inverters have a "limiter" function, where a CT clamp is placed between the system and the grid meter so that the inverter can ramp down its output to generate just enough power for local consumption without exporting any. This is mainly for use in regions where feeding into the grid is not permitted.

The whole idea with a grid tie inverter is that during the day you use the energy that is available from the solar and the surplus gets delivered back to the grid. In some places this pays decent money in others hardly nothing.

If you use a grid tie inverter powered by your power wall instead of solar panels, you need a way to limit its output, otherwise you are going to be powering you local neighbourhood from your batteries (unless your consumption is always more than the maximum output of the inverter).
