I have a few questions here.
1, as I understand it the battery isolator switch stays on with the exception of when in storage or batteries will be drained.
2, I purchased a Honda generator and when the trailer is plugged into the generator the isolator switch is left on ?
3 when using the inverter I just switch it on and don't have to change or shut anything off ?
4 when the trailer is plugged into the generator the converter will automatically charge the batteries without me having to change anything ?
5 when using the inverter I don't have to switch off the isolator switch ?
Thanks in advance for any advice on this , it's all kind of complicated to me.
1. The battery cutoff does just that. It cuts off power from the batteries to the trailer. If you don't cutoff battery power when storing the trailer, then certain components that are hard wired and don't have an on/off switch, (like the Carbon Monoxide detector) will be powered and can slowly drain the battery.
2. The generator provides AC power, just like when you plug in at a campground with electrical hookups. The only difference is that the small Honda 2000 generator can't provide 30 amp power, and it's peak output is 2000 watts. So, that means you can't run everything at once like you can when you're plugged in to 30 amp shore power. Just as you don't cutoff the batteries when you're hooked up to shore power, you don't cutoff the batteries when you're connected to a generator.
3. The inverter takes DC (battery) power and inverts it to AC (household) power. You only turn it on when you are NOT connected to shore power and are using battery power only - and you want to plug something in to an AC outlet. When you are connected to shore power, the inverter is not part of the picture, because your trailer's CONVERTER powers the AC outlets.
4. With a generator running and connected to the trailer, the converter's charging function will charge the battery. But, the charging capacity will be reduced if you are using the generator power for something else. When you're connected to shore power the converter will charge the battery as well.
5. Once again, you only use the inverter when you're not plugged in to shore power and want to use an AC outlet. If you cutoff the battery power, the inverter can't function - it has no DC power coming in, so it cannot output AC power.
An easy way to keep it straight is to remember that a CONVERTER converts AC power to DC. An INVERTER inverts DC power to AC. Once you understand that, the rest falls into place.
