2500W Inverter
Looking for an inverter for my 5th wheel. Around 2000-2500 watt. Don't want/need a charger or controller with it. Want to integrate with coach and remote on/off.... Not a hard core boon docker yet...

Just keep in mind if you go BIG on the INVERTER you better plan on it drawing ALOT of DC power from your battery bank. The 2000-2500 WATT INVERTER will draw between 160AMPS to 200AMPS from your battery bank. You will want to add another 50% draw to this number to be on the safe side. This will then be 240AMPS to 300AMPs of expected battery drain if the Inverter is fully loaded down.
When you check the RESERVE CAPABILITY specs on your battery bank you will find out how many minutes a typical 12VDC battery will produce power under load. They usually list it for a time period of producing 25AMPS. A typical GP27 Trojan 27TMX is listed as having a capacity to produce 12VDC for 175minutes (2.9HOURS) @ 25AMPS before dropping to 0% charge state. You can only use this for 1.4 hours to keep a single 27TMX battery from dropping below the 50% charge state to keep from doing internal damage to the battery. Bottom line is if you are only drawing 12VDC@25AMPS from four 12VDC 27TMX batteries in parallel they will only safely last for 5.6 hours. 25AMPS of power relates to around 300WATTs of drain.. Drawing a full 2500WATTS is going to drain your batteries MUCH MUCH more faster than these times listed... My only real experience test was a full Test Equipment load at a work site on a 1500WATT PSW Inverter direct connected to a standard rental car probably 105AH battery. It lasted only 15 minutes even with the motor running. I killed the alternator as well - rental car company had to bring us out another rental car on a flat bed truck haha... We denied everything...
You have to replenish what you take out of the batteries either using the Generator or the Solar Panels. The generator method is sure way to get it done quickly using smart mode charging techniques - the solar panels is a hit and miss as you can only expect high sun 5-6 hours a day to give max DC current.
Alot to think about here if you want to be successful EVERY TIME...
