Is the inverter universal from 12v to 72v

A1: No, 12V~72V cannot be converted to each other. You can only choose one of the input voltages, and the inverter input voltage must be consistent with the system input voltage. For example: a 72V inverter can only be used for a 72V battery. Q2: How to select the output voltage:

So when it comes to buying an inverter you will decide on either a 12v (for small loads) or 24v (medium to large loads). It will most likely have a modified sine wave output, with 220v PD. If you've never used a multimeter before then I wouldn't recommend you play around with electricity without someone with a bit of experience.

There are two main types of 12V inverters: sine and pure sine. Sine inverters produce a blocky signal, while pure sine inverters generate a wavy signal. Pure sine inverters are considered the best 12V inverter models because they produce a cleaner signal, which is better for expensive laptop and camera batteries.

The inverter's job is to turn power from DC to AC. 12V solar panels are applicable for small size solar system projects for: Most RV and motorhomes already have 12V batteries for AC, refrigerator, water heater control and lighting. So it makes perfect sense to use 12V for these type of systems.

A 12V solar panel must use with a 12V inverter and a 24V solar panel must use with a 24V inverter. On top of that a series connection is required to maintain the same voltage between the battery, inverter and the solar panel Check out 12V, 24V and 48V inverters here. To keep things simple, just remember to keep the voltage the same.

An inverter with a 12v input, if voltage is lower than 10.5v or higher than 15v. will automatically disconnect the power supply for protection. An inverter with a 24v input, if voltage is lower than 20v or higher than 30v. will automatically disconnect the power supply for protection.
