Hybrid Inverter BOM Suggestion logic
When creating a system, and on the system properties page, one can opt for a hybrid inverter. If the “Hybrid” inverter type is selected, inverter suggestions will include one (and only one) hybrid inverter.
The hybrid inverter being suggested is currently one of the following:
- MH3000
- MH3600
- MH5000
- LH6000
- LH10000
From these options Helios will pick the smallest one that is larger than the layout’s total module power. (If the module layout’s expected maximum AC power has been calculated, Helios compares it to the inverters’ maximum AC power; otherwise Helios compares the layout’s nominal power to the inverters’ nominal power.) If the layout power is larger than the largest option, Helios will pick it anyway, along with the cheapest inverter(s) that together have the required capacity.
Like non-hybrid inverter suggestions, Helios will check if the about-to-be-suggested inverters satisfy several other requirements, and will even attempt to come up with a potential string plan if the layout isn’t too complex. Only if Helios can generate a valid string plan, will it actually suggest the set of inverters; if not, it will try other sets of inverters until it can. So if your inverter suggestion includes a hybrid and a non-hybrid inverter even though the hybrid one seems to have enough capacity by itself, that’s probably because with only the one hybrid inverter no valid string plan is possible.
By default the hybrid inverter is added to the bill of materials without a battery. One of the applicable battery packs can be selected on the energy management page. This page can be found in the top menu: Results -> Energy management. It can also be found by clicking the link on the dedicated battery line on the bill of material page: Results -> Bill of material.
