C/Rating on batteries – a simple explanation.

The C rating of a battery refers to its discharge rate or the rate at which it can deliver its stored energy. It is typically represented as a multiple of the battery’s capacity. For example, a battery with a C rating of 1C can discharge its entire capacity in one hour, while a battery with a C rating of 2C can discharge twice its capacity in one hour.

To determine the C rating of a battery in your solar system when it is not specified on the spec sheet, you may need to gather some additional information and perform calculations. Here’s a general method you can follow:

  1. Determine the battery’s capacity: Look for the capacity rating of the battery on the spec sheet. It is usually given in ampere-hours (Ah) or milliampere-hours (mAh). For example, if the battery has a capacity of 100Ah, that means it can theoretically deliver 100 amps of current over one hour.
  2. Find the maximum continuous discharge current: Check if the spec sheet provides the maximum continuous discharge current rating. This rating indicates the highest current the battery can continuously deliver without causing damage or significant voltage drop. It is usually mentioned in amps (A) or milliamps (mA). For instance, if the battery’s maximum continuous discharge current is specified as 50A, it means it can deliver a continuous current of 50 amps.
  3. Calculate the C rating: Divide the maximum continuous discharge current by the battery’s capacity to calculate the C rating. Convert both values to the same unit if necessary. Using the previous examples, if the battery has a capacity of 100Ah (100,000mAh) and a maximum continuous discharge current of 50A (50,000mA), the C rating would be:C rating = Maximum continuous discharge current / Capacity = 50A / 100Ah = 0.5C

Therefore, in this example, the battery has a C rating of 0.5C, meaning it can discharge at a rate of 0.5 times its capacity.

Keep in mind that this method assumes the battery can sustain its maximum continuous discharge current without significant voltage drop or damage. It’s always recommended to consult the manufacturer or supplier for accurate information on the C rating if it’s not readily available.

Safety on your Solar Panels not to be taking lightly

DC arc refers to an electrical arc that occurs in a direct current (DC) circuit. It typically happens when there is a high voltage differential and a conductive path is created through the air or another medium. The intensity of the arc depends on factors such as the voltage, current, and distance between the conductive materials.

In a typical Installation of 8 x 550W solar panels connected in series. It’s important to note that solar panels produce DC electricity, typically at a voltage range of 12V, 24V, or 48V, depending on the configuration. The total power output of your 8 solar panels would be 8 x 550W = 4,400W (or 4.4kW).

If you are concerned about the potential for a DC arc occurring in this setup, it’s essential to ensure proper wiring, grounding, and protection mechanisms. Here are a few considerations:

  1. Wiring: Use appropriate-sized wires and cables to handle the current produced by the solar panels. Consult the manufacturer’s specifications or seek the assistance of a qualified electrician.
  2. Circuit Breakers: Install circuit breakers or fuses in the system to protect against overcurrent situations and potential arcs. Properly sized and rated breakers should be used according to the current capacity of the solar panels and wiring.
  3. Disconnecting Means: Include a disconnecting means, such as a switch or breaker, near the solar panel array. This allows you to isolate the panels from the rest of the system for maintenance or in case of emergencies.
  4. Grounding: Ensure that the solar panels, inverters, and other relevant components are properly grounded. This helps to minimize the risk of electrical faults and provides a path for fault currents to dissipate safely.
  5. Compliance with Codes and Standards: Follow the local electrical codes and standards applicable to your area. These guidelines provide specific requirements for the installation and safety of solar panel systems.

It is important to consult with a qualified electrician or solar installer who can assess your specific installation and provide appropriate guidance to ensure the safety and proper functioning of your solar panel system.

Pure Sinewave vs Modified Sinewave Inverters

Pure sine wave inverters and modified sine wave inverters are both types of inverters that convert direct current (DC) electricity to alternating current (AC) electricity, but they do so in slightly different ways.

Pure sine wave inverters produce a waveform that is a perfect sine wave, which is similar to the waveform of the electricity that is supplied by utility companies. This type of waveform is considered to be the “cleanest” form of AC power and is suitable for powering sensitive electronic equipment such as computers and televisions. Pure sine wave inverters are generally more expensive than modified sine wave inverters.

Modified sine wave inverters, on the other hand, produce a waveform that is a square wave or a modified sine wave. This type of waveform is not as clean as a pure sine wave, and can cause some electronic equipment to operate less efficiently or even damage them. Modified sine wave inverters are less expensive than pure sine wave inverters and they are suitable for powering devices such as lights, power tools, and motors.

In summary, if you need to power sensitive electronic equipment, a pure sine wave inverter is the best choice. If you’re looking to power less sensitive equipment such as lights and motors, a modified sine wave inverter is suitable and more cost effective.

AXPERT INVERTERS FROM VOLTRONIC POWER

AXPERT INVERTERS

Yes it is true, they look the same, got the same product codes, the specs are the same, and the fact is they are the same. Meccer, Kodak, RCT, Lux Power comes from the same company Voltronic Power.

These are very good products and becoming the leader in Power Solutions market and also for the close-to-be EV Vehicle era we are moving in. They supply a few of our local suppliers and brand it for them accordingly, there are also some smaller people importing it for their own customers which LTV Tech also working towards but there are a few things to consider. Buying and selling is one thing, but the warranty is a thing to look at and after-sales service is very important. Most suppliers will help but from experience in the marketplace, we at LTV Tech had really great after-sales service with our supplier Rectron which brands its products as RCT.

Here is also a very good explanation of how these systems work and how to implement and install it in your home or office.

Search on our website for RCT inverters and consult us on which specific inverter is best for your specific application
