# Solar Generator Trailer Quick Reference

## Security:
- The keys to the trailer are in a lock box attached to the front right side of the trailer deck on a large D-ring. 
- Contact Kyle DeHaas for access code. Do not change the access code.

## Startup:
1. Use the sprung pins on either side of the panel arrays to align the panels for maximum power. Usually orienting the trailer long side to the south and tilting the panels about 30 degrees works well. Make sure all four pins are latched closed once the panels are in position.
2. Next, notice the two yellow Sunny Island inverters. The left one is the "slave" and the right one is the "master". Find the black breaker switch on the front panel of the slave inverter and turn it upward to turn on. Wait for the slave to power up, then turn on the master inverter breaker next. This will place both inverters in Standby Mode, after a minute of boot time.
3. All control of the inverters is done from the master inverter panel, on the right. Anything you do to it, will also occur to the slave inverter, so you should not have to do anything with the slave inverter button controls. On the master, tap the <Enter> button briefly, then press and hold the <Enter> button, and this will turn on the inverters.

## Shutdown: 
Shutdown is basically the reverse of startup. On step 3 above, tap, then press and hold the <Enter> button to bring both inverters back to standby mode, whereupon you can shut off the breaker switches on the front panel of both inverters.

## Travel: 
The solar panels must be vertical during any trailer movement, and all 4 latch pins closed. The inverters should also be turned off.

## Long Term Standby:
For storage and idle time, the breakers in the photovoltaic combiner panel should remain on so that the solar panels and Midnight charge controller will float charge the batteries. 

## Battery Maintenance: For Lead/Acid battery banks
Perform Monthly: There are two battery banks of 24 cells of 2 volts each. Batteries should be checked to make sure water levels are correct.  
- Wear protective gear (gloves & eyewear) to prevent exposure to battery acid.
- Use distilled water to fill. 
- Use the battery water filling container in the box in the front of the trailer. 
- Open the cap on each battery and check the level. Add water until the water just reaches the bottom of the fill neck, or covers the top of the highest lead plate, and no further. Do not over-fill. Do not let contaminants get into the battery. Replace the cap securely.

## Power interface and breaker configuration:
1. For 240 volt operation, you'll need a cable that terminates in NEMA SS2-50P to plug into the trailer's NEMA SS2-50R outlet. This is also known as 50-amp 240 volt twist lock male plug, or "California Style plug".
2. Inside the inverter panel box, notice the MidNite Classic charge controller. To its right is the photovoltaic combiner panel. These should be on at all times, unless there's an emergency. Open that panel and turn on all the breakers by switching them upward. This brings solar power through the charge controller, and to the batteries to keep them charged.
3. Open the breaker panel to the right of the slave inverter. Turn on all the breakers by switching them upward. This will bring power to the 50-amp 240 volt twist-lock outlet (NEMA SS2-50R style), and the 15-amp 120 volt outlets. These should stay on all the time as well, in all situations except an emergency.
