Any WIFI battery voltage monitors?
It should. The lower you go in frequency the more it will penetrate things. Thats why 2.4 ghz and such has a hard time going thru things. 433 mhz is very good at penetrating things. 2.4ghz came about with the need
Battery at 12.3v under load. When load removed
The 12v marine "deep cycle" batteries are only modestly more able to withstand deep discharges than regular starting batteries. Disconnecting the heavy loads when then voltage hits 12.3v will definitely help them last longer, but they won''t actually be discharged to 50%, which is good, as those will die quickly if cycled that low.

Serial vs parallel Panels
Your panels are a bit higher voltage than typical "12V" panels, which might be 17 Vmp and 21 Voc, so could be connected in series. Parallel should be good for your panels and 12V battery. If you expand the system, consider the wide range of brands and voltages available (and support for 24V & 48V batteries, and various chemistries.)

6 FAQs about [12v solar system and 3v]
How do 12V solar panels work?
For a 12V system, you’ll typically use panels rated at 12V nominal voltage. Charge Controller: This device regulates the flow of electricity from the panels to the battery, preventing overcharging and extending battery life. 12V Battery: This stores the energy generated by the solar panels for use when sunlight isn’t available.
What are the components of a 12V solar charging system?
Basic Components of a 12V Solar Charging System A basic photovoltaic (PV) solar electric panel system for 12V battery charging comprises a solar panel connected to a charge controller, connected in turn to the battery. PV Solar panels The amount of power that a PV solar panel provides is indicated by the wattage (W).
What is a 12V Solar System?
12V systems excel in simplicity and compatibility with many DC appliances, making them ideal for mobile and small off-grid applications. 12V solar systems offer a flexible, efficient, and environmentally friendly power solution for a wide range of applications.
How to choose a solar panel for a 12V battery?
Choose a solar panel whose open circuit voltage matches the battery charging voltage. Meaning for a 12V battery you may choose a panel with 15V and that would produce maximum optimization of both the parameters.
How much energy does a 12V Solar System use?
In our example: 185Wh x 3 = 555Wh or 46Ah for a 12V system. Select appropriate solar panel wattage: As a rule of thumb, your solar panel wattage should be at least 1.3 times your daily energy usage. In our example: 185Wh x 1.3 = 240W of solar panels. As your energy needs grow, you can easily expand your 12V solar system.
