I have installed this system in December 2019, following Will's All-in-One system guide.
Been using it to power my internet router and laptop when there is no electricity, and as UPS here since the electricity fluctuates a lot here.
Overview:

Doubts & problems with the battery type settings:
I'm having some problems with the AGM battery, it's discharging faster now after discharging it to low voltage, the unit used the low voltage cut-off function like 3 times in last 2 weeks, never happened before, the first time this happens was 2 weeks ago, I was gaming on the laptop for a long time and did not notice the voltage was going too low, it was cloudy, I have the settings on battery type as AGM default settings, but I'm not sure what is the low voltage cut off for that, I will be pleased if somebody helps me with that, just noticed that you can only change the low voltage cut off on the User-defined settings.
I think I will be fine with the AGM battery for a couple of months, even that it is discharging faster, I keep the AGM battery settings but I'm open to suggestions for User-Defined settings to preserve the battery life.
Future Upgrades:
I'm planning to buy 2 more 100w solar panels to connect them in series for 400W, I think it will be safe as Max Open circuit voltage is 102, and the panels usually have 20-22v each, correct me if I'm wrong pls, I will appreciate it![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
I will need to replace the battery later, even if the battery is fine I don't think 100ah will be enough in some situations where I have long periods without electricity, one or 2 days some times. I don't want to buy another AGM since everyone suggests buying Lifepo4 and it seems to be the best choice, they are not cheap either, I can't afford it right now but I'm planning to buy one by the end of the year, maybe a BattleBorn, it cost a lot of money but I think it worth to have something good and durable, we will see if there are better options later.
Also, it will be a good idea to add a breaker to the solar panel, and AC cables to protect the system.
