Wiring your Energy Equipment and Accessories

How to get an Independent Power Grid working:

Setting aside that to be TOTALY independent you need Solar and Battery modules, a small 3.5kW Generator would obviously provide black-out security, and any other other forms of Generation you choose to use, like Wind & Aqua.

The Wiring of your system correctly is the most important step to getting the system operating and correctly producing the required power, if you are handy you can do most of this work yourself, however you should engage a qualified electrician to inspect & approve the system before going live !

Once your solar & Battery storage installation is complete you will instantly start saving, all done by not having to pay for importing the power you consume.  If you invest in an oversize battery bank, you many not require a Diesel generator as back-up, especially if your Solar array & Battery bank is sufficient to cover all your power consumption.

However, being able to use the state grid as your go-to for back-up power supply, means you will have to pay for the monthly connection fee, and if you happen to receive a feed-in tariff, that may cover that annoying & deceptive connection expense to remain State grid connected.

Remember: It's simple to calculate totally power independent, when using correctly sized Solar array & Battery storage!

First Stage of every Micro Grid is the convergence of PV array string(s) by optimising your solar system wiring, this will improve the PV power efficiency.  A Hybrid Inverter comes with all the system management tools you may ever need, and Pre-Installed/wired Lightning/Surge Protection & pre-tested Module.

Wiring batteries is very simple, as long as you use DC isolator switches, using AC isolator switched on DC voltage is NOT safe, especially high DC voltage can arch across an AC switch terminals causing a short with a high possibility of the AC switch gear catching on fire!

Once you have decided on your battery bank DC voltage and kWh capacity that should largely depends your power usage after sunset to the next sunrise.

Remember: Commonly the higher the DC voltage the better, for either charging/discharging for any system.

It is more common that newer 'Hybrid Inverter', have multiple inbuilt MPPT software, this controls PV shadowing or low light conditions, thus keeping your power more stable.

This subject is covered in more detail on the Diesel Generator page, But basically a Hybrid Inverter with Automatic Generator Start (AGS) feature is standard on many newer Hybrid inverters.  Recently, using Bio-Gas for generation is becoming a serous player in the renewable energy market.
