Short answer “yes”. We have made sure there is a battery compatible option available in the Perth Solar Warehouse store to suit your Perth Solar Warehouse solar energy system.

Long answer in a nutshell: The primary purpose of the intended battery storage system must always be considered to determin if a solar energy system is accurately battery ready for the desired intention. The question a customer should consider in conjunction with the above is, “what do I want a battery storage system for?”.

The 2 most common answers for most Perth Solar Warehouse shoppers:

  1. To store solar generated electricity for later use during peak consumption periods outside of sunlight hours.
  2. A back-up power supply in the event of a grid failure.

There is a difference in how these two variances are configured, specific battery requirements, load compatibility and more. As not all solar is the same neither are all battery storage systems and their intended purpose. Our team of tech guru’s can always help guide you for what’s best for your specific needs, now and in the future.

Good news is not a lot. However, this is largely dependent on the particular environment your solar panels are installed in. An element which is unique to every individual installation.

An extract from the SolarWorld solar panel user manual is as follows:
In general, the modules do not need cleaning if the tilt angle is greater than 15 degrees the panels will be self-cleaning by rain. In the case of heavy soiling, we recommend cleaning the modules with plenty of tap water or deionized water without any cleaning agents. If necessary a soft cleaning device (e.g. sponge, soft brush) may be used. In the case of soiling by dust or sand, the modules can be cleaned with a soft brush without using water. Never scrape or rub off dirt; this may result in micro scratches.

SolarWorld recommends regular inspections of the system to ensure that:

  1. All fixtures are securely tightened and corrosion-free;
  2. Wiring is securely connected, properly arranged and free from corrosion;
  3. Cables are free of damage;

Please also observe the current local standards.

The fault code 74 means there is a defective Varistor.

Varistors protect the electronics against energy peaks, such as those that can occur in the event of lightning strikes in the neighborhood.

Varistors diminish with repeated strain as a result of overvoltage.

What to do: Contact an installer or SMA solar power professional.

If your solar panels have gathered dust or dirt, there is a cleaning procedure. Only use water to clean your solar panels, using chemicals can create a film on the glass which can hinder performance.
