If you’re wondering if you can parallel two non-inverter generators, you’re not alone. A large number of homesteaders have tried this method, and some have had great success. However, there are some disadvantages and problems with paralleling non-inverter generators.
Using a parallel kit
A parallel kit is an accessory that can be attached to two inverter generators to produce more power. When the two generators are in parallel, the power from both units combines before going into the load receptacle. This allows the power output from each unit to double before being sent to the home, business, or RV. This type of kit can be used for different brands and models of generators. However, it is important to note that the wattage and voltage of the two units should be similar in order to ensure a good connection.
Parallel kits are very simple to install and use. Anyone, including non-technical users, can install them. The parallel system monitors load share and automatically matches the burn rate of each unit when the load increases. This helps prevent overloading of one unit and instability of the system. You can find numerous different sizes and brands of parallel kits on Amazon.
Using a synchroscope
If you want to parallel non-inverter generators, you can use a synchroscope to do it. A synchroscope works by measuring the difference between two different voltages or currents. The difference between the two voltages or currents is called the phase angle, and can be measured in degrees. When the phase angle is exactly 180 degrees, a generator will be in phase with the grid.
A synchronscope is an instrument installed at the main switchboard that indicates whether two electrical supplies are in phase with each other and can be paralleled. It can measure voltage, frequency, and phase angle. It is important to keep the synchronscope in the circuit for at least 20 minutes. A synchronscope is an instrument that consists of a small motor with two poles. It is connected to the red and yellow phases of the incoming machine and to the red and yellow bus bars of the switchboard.
While using a synchronizer is an excellent option for paralleling non-inverter generators, it can be expensive. It is also not possible for non-inverter generators to work in parallel without a synchronizing panel. A synchronizing panel matches the frequency and speed of the generator to the electrical grid. Unless they match, the AC generator will not be able to deliver power to the electrical grid. It is possible to synchronize the two generators incrementally or fully.
Using a dead bus synchronization system
Dead bus synchronization is an electrical method used to parallel non inverter generators. This method utilizes a voltage regulator to provide an excitation ramp to each generator. This approach can help prevent the exchange of reactive power between the generators and reduces the start-up current for the generators. However, this technique is not recommended for all applications.
Using a dead bus synchronization technique to parallel non inverter generators can solve many problems associated with conventional paralleling. The first advantage of this method is that it allows for relatively fast paralleling of multiple engine-generators using a common bus. Another advantage is the ability to pull multiple generators into electrical synchronization as the gen-sets start up. This approach also provides an advantage over conventional paralleling techniques, as each gen-set can be paralleled to a common bus without putting mechanical stresses on the other.
The second advantage of dead bus synchronizing is that each machine can be set up to match the other generators’ frequency and voltage. Typically, these systems are installed in larger power systems such as transmission substations and industrial distribution systems. They are also used in microgrids.
Problems with paralleling non-inverter generators
Paralleling two non-inverter generators offers many advantages, including increased convenience, flexibility, and reliability. It is also safe, provided the generators are compatible. It is also advisable to follow manufacturer instructions when paralleling two generators. Fortunately, many generators are designed to work together, which makes paralleling an easy and safe process.
When paralleling two generators, it is important to observe the phase sequences and ensure that both generators start at the same voltage. It is important that the voltage amplitudes and phase angles of the two generators match, so that there are no electrical problems or potential damage. Generally, you should parallel only two generators, as more than two may cause compatibility issues.
For larger installations, a more powerful generator may be needed. In these cases, an inverter generator may be the best option. In general, inverter generators are more reliable and can protect sensitive electronic devices. In some instances, paralleling a pair of non-inverter generators is acceptable, as long as they are compatible in both amperage and voltage.
