RESISTORS FOR SOLAR INVERTERS. Many resistors are used in a solar inverter circuit- see Figure 10. Current requirements focus on high voltage, high efficiency for energy saving, and long lifetime. For the resistor, this means high reliability with long lifetime, high voltage-withstand capability and high accuracy.
Dummy loads resistors transfer the excess energy into heat and release it into the environment to prevent the solar panel from overloading. Cressall offers a large range of different varieties of high-power dummy load banks that can be customised for diverse applications, such as low noise versions for urban locations.
PIRs are a three-phase resistor, insulated for the full system voltage, typically 33kV and fitted with isolating devices as required. PIRs have a high thermal mass allowing them to absorb energy from high inrushes while still being compact enough to fit efficiently in a transformer substation.

6 FAQs about [What kind of resistor is best for solar power generation]
What is a Pir resistor?
PIRs, such as those offered by Cressall Resistors, are a three-phase resistor, insulated for the full system voltage, typically 33kV and fitted with isolating devices as required. PIRs have a high thermal mass allowing them to absorb energy from high inrushes while still being compact enough to fit efficiently in a transformer substation.
What are the different types of PV inverters?
The most common PV inverters are micro-inverters, string inverters, and power optimizers (See Figure 5). Figure 5. Microinverters are connected to each solar panel, which are connected in parallel, and convert DC directly to AC. String inverters are used with multiple solar panels connected in series.
What does a PV inverter do?
PV inverters serve three basic functions: they convert DC power from the PV panels to AC power, they ensure that the AC frequency produced remains at 60 cycles per second, and they minimize voltage fluctuations. The most common PV inverters are micro-inverters, string inverters, and power optimizers (See Figure 5). Figure 5.
Should a solar cell use a short circuit current?
Given the linearity of current in the voltage range from zero to the maximum power voltage, the use of the short circuit current for cable and system dimensioning is reasonable. One way to measure the performance of a solar cell is the fill factor.
What are the advantages and disadvantages of solar PV power generation?
There are advantages and disadvantages to solar PV power generation. PV systems are most commonly in the grid-connected configuration because it is easier to design and typically less expensive compared to off-grid PV systems, which rely on batteries.
What are the different types of solar array mounts?
Figure 4. Typical solar array mounts include roof, freestanding, and directional tracking mounts on the roof or on the ground. Image courtesy of Greensarawak Roof-mounted solar arrays attach to the roof rafters and are engineered to handle the same forces and climate conditions as the rooftop.
