On average, the amount of required roof space for a set of home solar panels is between 300 sq ft and 500 sq ft total. When looking into a system for your home, the amount of required roof space will be dictated by the number of solar panels you plan to install. However, limited roof space can also limit the potential size of your installation.
The average residential solar panel size is about 17.5 sq ft—though it's good to overestimate the area required as some installation space is necessary between the panels and rows. When installing 22 panels like in our example, and each panel takes up about 18 sq ft, your system would require approximately 396 sq ft of roof space.
Our solar panel calculator helps you determine how many solar panels can be installed on your roof and how much electricity they can generate. It calculates the maximum number of panels that fit on the available roof surface, taking into account important factors such as orientation, inclination, and panel type.
Standard Efficiency Panels (350-400W) These panels represent the most budget-friendly solar options and work well for homes with ample roof space. Modern standard efficiency panels from quality manufacturers deliver reliable performance at lower upfront costs. For a typical 7 kW system, expect to need 18-20 panels in this category.

If lithium batteries have been deeply discharged they should be charged at a very low rate until they reach their minimum voltage above which they can accept the usualy high currents. So this sounds like a protection feature to me to prevent damage. but your batteries should never be seeing a low voltage disconnect event!
If the voltage doesn't exceed 13.5v that'd be a bit weird and counterintuitive to having a boost voltage of 14.4. Think of it like if the battery is below 14.4v the controller will throw as much wattage as possible at the battery.
Bought 3 Rover Elites and that POS goes into a "overdischarge protection" mode if the battery gets too low, but when the panels come back up again, it won't start to charge again. Panels meter at 70V input and that controller won't come out of it's sulk and do it's job.
Once the battery reaches 14.4v the controller “equalize/float” and will only give the battery as many watts as it takes to maintain that 14.4v (usually for a set time,2hr is standard). I believe ampere time balance voltage is 14.2-14.6v meaning if the battery never gets there it'll never have time to do any balancing.
Match your power needs to station capacity: 100 Wh for backpacking, 3,600 Wh for car camping and RV adventures. Verify that output ports match your devices—USB, AC outlets, and 12V DC connections. This RV solar sizing guide walks you through every step — from estimating your daily energy needs to choosing the right panels, batteries, and charge. . To size your solar panel, calculate your daily energy use in watt-hours and divide it by the peak sun hours in your area. A small cabin might need a 400W panel, while a larger one could require 1200W or more. It's simple and straightforward to use.
