Installing a small off-grid system is the choice of most people, which gives you the freedom to use electronic products such as laptops, coffee machines, refrigerators, etc. during your outdoor trips. The installation of a small off-grid system is not complicated. Prepare a few batteries, a converter, and an inverter to assemble a set of inverter power supply system. If you want to use electricity unlimited, it will be practical to have solar panels on the roof.

Sizing Your Inverter for Your Needs
Selecting the power of the inverter is a key step, taking into account the effective meeting of electricity demand and economic benefits. You need to choose the power of the inverter according to the wattage of the equipment that needs to be powered. There is a very simple calculation formula: inverter power > total load power of electrical equipment. Calculate the sum of the power of all electrical equipment in the car, and you can roughly get the power of the inverter required. It is worth noting that the power consumption during the working process of the inverter and the peak power when the appliance is started need to be considered in order to prolong the service life of the inverter and electrical equipment.

The conversion efficiency of BPlus series inverters in 12VDC and 24VDC systems can reach 88%, and 48VDC systems can reach more than 90%. If BPlus2000W, 48VDC systems are used, the total power of electrical equipment can be within 1800W. In addition, BPlus series inverters have 3 times peak power, anti-reverse connection, over-voltage protection and other functions, which can effectively protect electrical equipment.

Why Not Just Get the Biggest Power Inverter You Can Afford?
The first is efficiency. Larger inverters tend to be less efficient than smaller inverters, and they tend to consume more power when idling (not running a load). When you’re off the grid, sometimes battery capacity per Ah matters, so there’s no reason to spend the excess.
Another major reason is cost – as inverters get larger, the price of inverters can rise rapidly. If you’re only consuming 600W at a time, buying a huge 3000W inverter might be a waste of money.

What to Look for When Choosing a 12V Inverter for Your Van
Some properties to know about inverters:

1. Continuous output power. This is what the inverter can output continuously.

2. Peak/Surge Power Ratings. This is what the inverter is able to output for a short period of time or “surge”.

3. Efficiency class. This is the overall efficiency of the inverter.

4. No load/idle consumption. This is the amperage the inverter draws when it is not powering the load.

5. The safety function of automatically turn off. At the very least, if the inverter detects that the battery voltage is too high/low, the AC input is overloaded, and the inverter starts to overheat, it should automatically shut down.
Also, make sure it has standard compliant certifications and certificates.
