QUESTIONS ABOUT THE OPERATION OF THE POWER OPTIMIZER M500
You can find an explanation of how it works on our product page: Product – BRC Solar GmbH (brc-solar.de)
The minimum input voltage is 16 volts (see data sheet).
The maximum efficiency is 99.5% (see data sheet).
There is no minimum limit. The optimizer can lift even the smallest currents and thus greatly reduce the voltage in the same proportion.
Our optimizer is a DC step-down converter. This means we can only reduce the voltage to increase the current. A reduction of the current is not possible.
With the help of our planning tool, you can find out whether the planned number of modules can be installed (including the required number of optimisers) without falling below the minimum input voltage of the inverter.
The measurement of protective conductor resistance and no-load voltage is possible without any issues. During insulation measurement, attention must be paid to the poles to avoid a short circuit. Conducting a pure short-circuit current measurement is not permitted.
If neither side has significantly more modules than the other, both sides are problematic half the time and would slow down the other. That is why you always need optimizers.
We are not aware of any problems with use near railway tracks.
Questions about mounting the Power Optimizer M500
The optimizer is equipped with original Stäubli MC4 connectors and has plug & play functionality. It is connected in parallel to the module. You can find more information about this in the assembly instructions.
No, the BRC Power Optimizer can be used flexibly and can be connected to single or multiple shaded modules as required. Modules that are not shaded do not need to be equipped with the optimisers. This is the great advantage of the flexibility of our product.
However, for different alignments or different module inclinations, we recommend full equipment.
There is no minimum number of optimizers in the strand.
Yes, it is possible.
In principle, it depends on the open-circuit voltage of the modules. This is added when two modules are connected in series. In general, however, the recommendation is to connect the Power Optimizer to only one module.
With two parallel strings, both on the same MPPT, the behaviour of the optimisers is not clearly predictable.
– Either the optimizer is activated in the one string 
– Or the optimizer is not activated at all in order to keep the voltage of both strings equal.
Clear recommendation: Do not use with two parallel strings with only one MPPT.
No communication with inverter to be set up necessary. Our Power Optimizer M500 works with a plug & play function.
The open-circuit voltage indicates that an optimizer or a module has failed. Further detection would only be possible using a thermal imaging camera (hot spots in shaded modules).
Yes, it is possible, even without reducing the EEG remuneration.
Questions about compatibility with inverters and modules
The BRC Power Optimizer is compatible with all common inverters. You can find a current list here.
Yes, whether hybrid inverter or normal string inverter has no influence on the functionality of our optimizer! The only important thing is that it operates MPP tracking.
No, the Power Optimizer M500 can not be used with microinverters.
Basically no change of settings necessary, optimisers always work. Depending on the type of inverter, efficiency can be improved if e.g. the shadow management is switched off
– Kostal on
– Fronius off (with full optimisation)
The BRC Checker app (available in the Playstore, App Store and as a web version) can be used to check the compatibility of modules. The power, the rated current and the open-circuit voltage are particularly important. This data and the temperature coefficient must be entered. This provides direct feedback as to whether the optimiser is suitable for the module. The data can be found in the data sheet of the corresponding module.
Questions about upcoming features
Further optimizers with adjustment of the performance classes are planned. Subscribe to the newsletter to make sure you don’t miss anything.
Monitoring via app of the individual optimizers is planned and will appear in the course of 2024.
The current Power Optimizer M500 does not have this function at the moment. However, the function is conceivable for the future.
