DIY Off-Grid Systems

14 Jul 23

If basic procedures are followed very successful small wind & solar systems can be self installed. Indeed, sometimes in remote areas there may be no choice!

Often DIY installation can reduce costs and can also mean users understand their systems better, so gaining most benefit from them.

However, electricity & wiring may not be for everyone, can be dangerous, and mistakes can be expensive! Particularly for systems including an inverter an AC power, an experienced electrician or installer should supervise or undertake the work. In all cases systems should be installed according to local electrical and other safety codes.

Consequently, most off-grid systems require the involvement of a professional electrician to ensure a safe and compliant installation.

We work with a large network of installers, many of whom we have known for a long time and who have received training at Wind & Sun so we can usually recommend an good local installer to you who can help.

DIY 12 and 24 V DC Systems

These are typically used on remote buildings to power 12V lighting and low consumption appliances or in situations where an existing battery based system is in place (e.g.. vehicles, boats & caravans) or to run small dedicated loads (e.g.. remote lighting, telemetry or monitoring equipment).

The wind generator or solar PV panels charge the battery and the battery supplies power to the loads as needed. All loads are run at the battery voltage (usually 12 or 24 VDC) and special lights or appliances are needed. The charging source is sized to keep up with anticipated demand.

Typical DC loads include:

  • lighting - using LED lights;
  • phone charging;
  • TV; radio;
  • pumps;
  • fans.

To be successful, efficient use of the electricity generated is essential and the system must be sized to meet worst case conditions.
