Off-the-grid inverter options?
« on: December 23, 2015, 02:48:35 AM »

Has anyone found a solution for using a 2013+ Zero S/DS/SR monolith battery as an off-the-grid power source / as an emergency AC power source?

I found this inverter thing poking around online:
http://www.zlpower.com/products_view.asp?/163.html

The PSC 6KVA-96 looks like a 2U device about a foot deep that would work with the 96-118V range of the 2013+ Zero S/DS/SR monolith battery.

Has anyone already tried to set up such a solution?

For the 2013+, no real need for a specialized input voltage inverter... in fact ALL inverter could work...  ;)

let me explain, a typical inverter convert DC input to another DC level and then switch it into AC with mosfet switching ON and OFF  with pulse width modulation.

So you can take the 102V nominal and connect it directly to most inverter DC HV section ... so you skip the low DC to High DC voltage convertion...

What is noce is that 102V if close to the usual 115V DC that most 12V input inverter convert in the HV dc section... you will get 102V AC instead of  115V but it will work on most device.

Personally i did that on a 1000W inverter and it does work... however on some inverter you might need a to supply 12V to the 12V input to have the control circuit to work.. a good trick to do that is to use normal low cost 100-240V input 12V ac power supply... and connect the AC input to the 102V of the Zero.  these work in AC and DC input.

I would first start with an energy audit ... and decide what exactly you plan on running when the power goes out.
Then I would look into cobra 12vdc 1000w inverters when you realize all you will be able to run is your fridge for a couple hours and some LED lights ;)
You car can keep you powered likely longer than your bike could.

On another note if you get 12v LED lights you can simply run them right off the bikes
DC:DC 300w converter ... 300w is a lot of LED light. My shop lighting in the garage is 35w and it is shocking how bright it is. 

Other things to consider (if your taking this seriously)
Do you have a blackout kit in several locations in the house, and does all the family know where they are? (I like the lights you plug into sockets and when the power goes out they turn on for intermediates to safely get to your blackout kits)
Do you have a 72 hour kit for every member in the family?
How will you take care of waste if the sewage system goes down?
Do you have an extended pantry and if so how long would it last if you were trapped at home?
Do you have a binder at home and in your vehicles which show escape and meeting points if your family has to get out of their house for any reason?
Do you already have a chest freezer you have filled the bottom with water bottles in case there is an outage?
Do you have a chest freezer you converted to a fridge because it is like 10x more efficient than your fridge?
Do you have water stored up and a way to filter water if you need to? (5 gallons a day per person is the average amount of use)
Do you have a method of cooking / heating food without using a microwave or electric range oven?
Do you have a method of saying warm / cool?
Do you have policies and procedures in place for if the power goes out and have you trained everyone in the family on how to safely use the inverter (I know you don't have it yet but seriously think about this as you might not always be around and or able to assist and someone could get hurt or make things worse)

You have opened Pandora's box my friend ;) The key is not to freak out over any holes in your plan (assuming your taking this seriously) I might have uncovered. Think it through and make a plan while crossing it off :D

I am sure I missed some things but you get the idea.

Very curious about this-- any links to expand on this?  Thanks

You'd be better off having a bank of deep cycle batteries as a back up, if you have room, which are cheaper. Then you can charge your Zero too!

Google is your friend ;)
But here are some examples
http://mtbest.net/chest_fridge.html (includes pdf of full article and parts list)
http://newlifeonahomestead.com/convert-chest-freezer-to-fridge-solar/ (this one goes in to the cons / adjustments one needs to make for this to be a lifestyle choice)
http://thundering-heard.com/2012/08/25/in-praise-of-chest-refrigerators/ (kilo-watt comparison)

http://www.instructables.com/id/Convert-a-chest-freezer-to-kegerator-or-fermenter-/ (kegerator acts as fridge as well)

People use these on offgrid projects since the energy "cost" to run them are so low.

120-VAC, 60-Hz OUTPUT
105-140VDC INPUT

Compact and rugged, the 1000-VA Model 1735 dc-to-ac inverter is designed to perform equally well
in stationary and mobile applications. The inverter provides an isolated, regulated 120-Vac, frequencystable
60-Hz quasi-sine-wave output and is available in 24, 48 and 130-Vdc input versions. The conservatively
rated Model 1735 can operate continuously at maximum rated power over a -10°C to +50°C
ambient temperature range. It is well suited for powering a variety of loads, from sensitive electronic
equipment to small motors and nonlinear loads normally considered difficult for inverters.
The Model 1735 is available as a plain inverter or with built-in automatic load switchover features to
permit operation in UPS or standby-power modes.

SPECIFICATIONS
Input Voltage and Current
The nominal input voltage, the input
voltage range, the no-load input current
and the full-load input current are
shown in Table 1.

Output Voltage
120 Vac nominal, single phase

Frequency
60 Hz nominal. ±0.25 Hz maximum
variation over the full range of load and
input voltage changes. Temperature
coefficient is ±0.02% maximum per °C.

Volt-Ampere Rating
1000 VA

Output Voltage Regulation
Approx. ±5%

Output Voltage Wave Shape
Three-level stepped approximation to a
sine wave with peak, average and rms
values approximating those of a sine
wave.

Temperature Range
Operating: -10°C to +50°C
Storage: -40°C to +95°C

Protection
Protection against overloads and
accidental short-circuit of the output is
provided electronically, and recovery
is automatic upon removal of the
abnormal load.
