Solar Inverters
The inverter is the component most often undersized, because it is the one sized by power rather than by energy. This category covers the choice between string inverters, microinverters and hybrids, how to size one against your real loads and surges, and the mistakes that cost DIY builders an inspection or an inverter.

String Inverter vs Microinverter: Which One Should You Choose?
One shaded panel drags down a whole string. Microinverters fix that at roughly double the cost — here is when the shade is worth paying for.
Read guide →Hybrid Inverters Explained: Do You Need One for Battery Backup?
A standard grid-tied inverter shuts down in an outage even with a battery attached. The hybrid is the component that lets the two work together.
Read guide →How to Size an Inverter for Your Solar and Battery Setup
The inverter is sized by power, not energy — and by the surge of your largest motor, not your average draw. The formula and the trap, worked through.

For anything with a motor, a compressor or sensitive electronics, yes — modified sine runs them hotter and shortens their life. Here is what actually breaks.

They are not the same hardware with a setting changed. One synchronises to the grid and dies without it; the other creates its own AC and cannot legally export.

Cold-weather voltage, surge duration and an unlisted model are the three that cost the most — and all three are decided before you order anything.
