How to Fuse a Power Inverter
If you have ever wondered how to fuse a power inverter, you are not alone. Many people have questions about this process and how to properly do it.
This blog post will provide you with a step-by-step guide on how to fuse a power inverter. By following these simple steps, you can ensure that your power inverter is properly fused and will work correctly.
Step 1: Tools Needed
- Head Screwdriver
- Soldering iron/gun
- Fuses (either 80 – 400 Amps for 450 to 6000 watts inverter)
- Tweezers/Needle nose Pliers
Step 2: Removing the Screws
Now locate and remove all the screws, and place them in a safe place so you do not lose them. Next, you will need to remove the inverter from the mounting bracket. Be careful when doing this, as there are still 2 wires attached to the inverter. Once the inverter is removed, you can now proceed to remove the old fuses.
Step 3: Take Apart
After removing all the screws, apply hard pressure while holding the inverter’s end in your hands with the plugs. Lift off the end cover simultaneously while being mindful of the two tabs. Afterward, park the white connector, this wire leads to the power indicator led, and detach it. Grab the inverter’s black end, then slowly slide it out of the shell. This part can be tricky. Try not to damage the white connector, or you run the risk of having to buy another inverter.
Step 4: Remove the Old Fuse
Removing the guts from the casing can be a bit difficult, if not done properly. Carefully lift the black part to expose the fuse. Heat the solder joints to remove the blown fuses before soldering them. Use Solder pump or De soldering wick to remove excess Solder fuse holes.
Step 5: Replace with The New Fuses and Reassemble
To properly heat and solder your fuse, first heat the joint with a soldering iron. Then, insert the fuse and flow solder into each joint. Repeat this process for each fuse. Once all the joints have been soldered, inspect them for bridges. If all the joints are clean, then reinstall the fuse in reverse. Be sure to plug the LED back in.
Do I Need to Fuse My Inverter?
Yes, definitely. If your inverter is old, there could be insufficient charging of the batteries, thus causing excessive voltage fluctuation.
Overcharging the system, due to excessive voltage fluctuations, may damage the batteries. Also, the inverter and battery system may fail to operate properly.
If a battery overcharges, there is the possibility of internal damage, which can lead to a fire. The fuse protects the inverter from overcharging, higher-than-normal voltage, and excessive current.
A fuse in the inverter’s battery string prevents possible explosion. The fuse in the inverter protects its circuit board, which may become damaged if the battery string is overcharged.
A fuse in the inverter’s battery line protects both the batteries and the inverter from overcharging because of higher-than-normal voltage.
What Size Fuse Should I Use for Powering a Inverter
When choosing a fuse for an inverter, it is important to consider the manufacturer’s recommendations as well as the current and voltage rating of the device.
In general, a higher current rating will be required for a higher voltage inverter. The goal is to select a fuse that the inverter’s current draw will not overload.
A general rule of thumb is to use a fuse that is twice the wattage of the inverter. For example, if you have a 1,000-watt inverter, you’ll want to use a 200-DC Amps (2,400-watt) fuse.
If you’re unsure about what size fuse to use, you can always consult with a professional electrician.
Can a Power Inverter Blow a Starter Fuse
A power inverter can cause a starter fuse to blow if it is not used correctly. If the inverter is not properly grounded, the electrical current can flow through the starter fuse and cause it to blow.
Additionally, if the inverter is not properly wired, the electrical current can flow through the starter fuse and cause it to blow.
To avoid this, make sure to follow the instructions provided with your power inverter. Always ground the inverter properly, and make sure the wiring is done correctly.
In conclusion, a fuse protects the inverter from overcharging, higher-than-normal voltage, and excessive current. To properly heat and solder your fuse, first heat the joint with a soldering iron. For example, if you have a 1,000-watt inverter, you’ll want to use a 200 DC Amps (2,400 watts) fuse.
