It''s a bit confused about some of the stats on panels we have been looking at, for example, 100 watt 12 volts panel and 100 watt 18 volts panel. In the majority of cases there are no differences other than name. In the early days of solar panels they tended to be small and often were just directly connected to a 12V battery for charging purposes.

The 48V inverter needs at least 2 solar panels in series, if 3 solar panels are connected in series, the performance of more panels may be better. The voltage for charging the 48V battery depends on the maximum voltage of the charge controller. Is a 48V inverter better than 12V? 48V inverters and 12V inverters each have their own advantages.

A 12V 5A PWM or MPPT charge controller is required to keep the battery from overcharging. With this system you can draw 100W from the inverter for 3 to 4 hours or 200W for 1 and half hours.
Nowadays, big houses, especially off-grid, tend to use 48 volt solar panels. Keep in mind that your inverter has to be compatible with the voltage of this system to be used. A 48V solar panel can be used with a 12V system if you choose the right equipment for it — a controller and an inverter.
But connecting a different volt solar panel directly to a 12v battery can damage the battery permanently 18v solar panel will produce 22-25 volts under ideal direct sunlight conditions (open circuit voltage). Which you can see on the backside of your solar panel.
If you have four 120W 12V solar panels, they can be configured in any of the following: A series connection will only work if all the solar panels are 12 volts. You cannot connect a 12V 100W solar panel to a 24V 50W solar panel. If you join the two, the system output will be limited to 50 watts. You cannot join these panels in parallel either.
You cannot connect a 12V 100W solar panel to a 24V 50W solar panel. If you join the two, the system output will be limited to 50 watts. You cannot join these panels in parallel either. Doing so will cause the panels to overheat and might even cause a solar fire or arcing .
