Pictures SunForce Pure Sine Wave Inverter Install
Hi folks,
Here is my solution to to the inverter installation, keeping the inverter battery cables as short as possible, and out of the battery compartment area. I am waiting on Silicon Bronze bolts and 300 Amp Circuit break, But the unit works good, and I am glad I went with the 2500 Watt unit, because the Convection Microwave pulls 2200 Watts
Front - SunForce Pro Series 2500 Watt Pure Sine Wave Inverter (599.99 at Amazon)
Back
Wires coming from battery box, with disconnect switch. Waiting on 300 Amp Breaker

I guess I'm missing something. Why the 300-amp breaker? Where are you going to get 300 amps?

Orv,
Good question because people forget that:
Power (watts) = Current (amps) X Voltage (volts)
2500 watts = 208.33 amps X 12 volts
So the 12 volt supply need a high amperage breaker.

Yup, it the LAW! Ohm's law that is!

I don't know what amp fuse or breaker his inverter calls for but my Xantrex 2000 inverter/charger calls for a 250amp T type fuse or breaker. Some of the other Xantrex inverter/chargers call for 300 amp T type fuses.

I found this site from someone else on the forum. See Circuit Breakers on the left tabs... has all kinds.

It all depends on the wire size I believe. Places that sell inverter cables, seem to put 300 Amp Fuse with 2/0 cable. The fuse or breaker should trip before the wire can get warm, and definitely if something goes wrong like a short.

OK, nice looking install, now where does the other end of the yellow extension cord tie into? Would like to see pictures of that also. Does it feed the whole trailer?

That is NICE!!! What a monster! I have some questions though:
What kind of 300A breaker are you getting? Autoresettable, T-type fuse, etc.?
Will you please describe how you got the yellow 110v power cord to the microwave and if you have the television and DVD player connected as well? These are the primary electrical devices not available for with 12 volt on my rig and this inverter can certainly cover these. All other devices run off 12 volt already.
What gauge and how long of wire did you use from the batteries to the inverter?
Would you please explain why you included a disconnect switch besides the power switch that is already on the Inverter?

Here is what I did, there are two 30 Amp RV receptacles, the one on the left got the the 50 Amp Transfer Switch, which take in the shore power and the Left 30 Amp RV receptacle. The out put from the transfer switch goes to the EMS-HW50C which then goes to the circuit breaker panel. Since I feed all breaker, the need for the wall switch to shut off power to the Coverter so I don't have to keep flipping the breaker to the Converter when running the inverter.
The 30 Amp RV receptacle on the Right is the outer ended of the yellow cord (10GA service Cord). I just use the jumper cable to jumper Inverter output to transfer switch input. The reason I did it that way, is I can also use the jumper for the Honda 3000 watt generator.
Jumper Cable for Inverter. Recptials are labed "Transer Swtch Input" and "Inverter Output"
Switch for Converter and EMS-HW50C display panel. Switch off when ON Inverter, otherwise Converter ON for shore power or generator.
Transfer Switch in front (right behind the two RV 30 Amp receptacle) and EMS-HW50C is other box in back.

The cables from battery to inverter are about 5 feet. The installation guide say 1/0 for up to 6 feet, and I installed 2/0.

This is a place holder tell the 300 Amp circuit breaker arrives. I wanted something where I could kill the power quickly since I don't have the 300 Amp Breaker yet.

2500 watts = 208.33 amps X 12 volts

Actually it is worst than that, due power lost in the process. From what I read, you should use 10 volts to take into account the lost thru the invert, thus 2500 watts / 10 Volts = 250 Amps. Breakers and wire should be sized for 20% more than expected load, 1.2 X 250 Amps = 300 Amps.

One more question. If the batteries are in a seal container and vented outside, can the inverter be mounted in the front compartment without it being damaged? I would think that way you would have shorter battery cables which would result in less power loss. The vented and sealed battery box would prevent gases from damaging the wiring etc.

In general I would say yes, but venting is to prevent hydrogen gas from building up, which is explosive. You don't want to mix something that might spark (i.e. Inverter failure) with explosive gases. All Inverter Manufactures recommend isolation, from batteries.
My Cable runs to Inverter is not that long, and sized big enough to prevent any noticeable power loss. Most power lost is in the inverter itself. Most reading I did, said to use 10V instead of 12V when figuring Amps. So 2500 Watts / 120V = 20.8 Amps. DC Wire to Inverter will need to be able to 2500 Watts / 10V = 250 Amps. This accounts for loss inside the Inverter.

I noticed this install was about 2 years ago. How has it worked out for you since the install?

Has been work very well. Since I have the Montana stored about 20 minutes away from where I live, it is nice to always have power at the flick of a switch. The solar panels keep the batteries full changed (never over charge), so I never have to worry about dead batteries.
