Three limits decide inverter size before you compare quotes
Inverter sizing is the lowest of three ceilings: backup load draw, battery delivery and your supply connection. Work that order before comparing quotes.
Roof to Meter
Does a three-phase house need a three-phase inverter?
Whether one inverter can back up your whole house depends on your phase configuration and board layout, not your appliance list. Here is how to check.
What a structural check settles before your panels go up
A structural check settles whether your roof can carry solar panels as permanent load. It is a separate opinion from the electrical CoC. Here is how to tell.
Sizing the inverter around the fridge, Wi-Fi and gate motor
Backup inverter sizing starts with the essential-loads list, not the catalogue. How standby loads, fridge surges and kettle-sized resistors set the number.
Your big battery is only as fast as the inverter charging it
Your battery is only as fast as the inverter charging it. How C-rate, the PV-to-battery path and the winter sun window set your real system limit.
The inverter number your pump actually needs to start
A correctly sized inverter still trips when a borehole or pool pump starts. Match the peak rating and its duration to the motor load you keep on backup.
How Monitoring Data Shows When Solar Panels Need Cleaning
Stop cleaning panels on a calendar. Learn to read expected vs actual yield, per-string dips and rain resets so monitoring data decides when cleaning is needed.
What a hybrid inverter checks before switching to battery
What a hybrid inverter checks before it switches to battery — and why two quotes with the same panel and battery figures can be very different machines.
Don't book a solar quote until you've checked these
Before you request a solar quote, check the meter, the distribution board, usable north-facing roof area and winter shading. These findings become line items.
Why your lead-acid bank died early, and LiFePO4 may not
Lead-acid banks die early for one reason: depth of discharge and partial charging. Here is how cycle life converts into real years of backup service.
