The Shabazan electrical system is rather simple, yet perfect for my needs. It currently consists of a power station (aka ‘solar generators’) that is charged from the engine alternator (starter battery) or via a solar panel. The Shabazan starter battery is connected to a GoPower 1750 inverter which then feeds an off the shelf power strip. The GoPower is a modified sine wave, so it’s ok for the older Delta, but not so good for the more sophisticated Delta 2 Max. The pure sine wave output of the Delta 1300 feeds the Delta 2 Max.
With a total power storage of ~3800Wh I’m good for all my needs.
As you see, I take the 12v starter battery power then convert to 120v for feeding the power station. To the folks that say (rightly) that there is conversion loss using this method, I agree. However, as both power stations are fully charged at the end of each days driving, I am not concerned.
Battery Connection
The starter battery feeds the house through dedicated cables. Shabazan does not rely on a the negative body connection. Not shown is the inline 150Amp Fuse.
GoPower 1750
The two house batteries are fed by this inverter. Not super powerful, but plenty for what I use it for.
Inverter Shutoff
I can control the inverter from the driver’s seat. All I need do is remember to shut the thing off when I shut off the engine. I can probably get it wired to the engine, but it’s too much trouble right now.
Delta 2 Max
This powerful fellow (2500 Wh) can supply my AC with many hours of cooling.
110v to 12v 30 Amp
Because the Delta can only provide 12v 8Amp output, and the heater needs 10-12 Amp at startup, I needed to add this into the mix.
EF Delta
The Delta 1300 was on the leading edge of technology when I installed it. Today, it seems a bit quaint. No app controls, limited power I/O – but Hey, It Works!
120v switch
A simple power strip is all that was needed to route power from the inverter to the power station. I can also run my Microwave from this. As it only runs for a minute or so, it’s acceptable.
12v Distribution
Rather standard in all van builds. Not much to say here.I do have another on under the sink, and again in each back corner.
