Panels get the attention, but the inverter is what actually makes a solar system usable – it converts the DC power your panels generate into the AC power your home runs on, and manages how that power flows between panels, battery and the grid.
String inverters vs hybrid inverters
A standard string inverter just converts panel output to usable power – fine for grid-tied systems with no battery. A hybrid inverter also manages a battery, deciding in real time whether to use solar, battery or grid power, and is what you need if load shedding backup is the goal.
Sizing an inverter correctly
An undersized inverter bottlenecks your panels’ output; an oversized one wastes money. Sizing depends on your panel array’s total output and your household’s peak simultaneous load – not just total daily usage – which is why a proper site assessment matters more than a generic package.
Common inverter problems
Nuisance shutdowns are usually a firmware or configuration issue rather than a hardware fault. Reduced output over time often points to a battery reaching end of life rather than the inverter itself. An inverter that won’t switch to battery during an outage is almost always a wiring or configuration fault, not a broken unit.
Frequently asked questions
How long do solar inverters last?
Most quality inverters are rated for 10 years, roughly half the lifespan of the panels themselves, so budget for one replacement over a system’s life.
Can I upgrade a string inverter to a hybrid later?
Usually yes, though it depends on the existing panel wiring and inverter brand – we can assess an existing system before quoting.
