Most expensive off-grid mistakes happen before the system is even installed
A lot of beginners start by buying panels, batteries and an inverter.
But without properly sizing the system first, it's easy to spend money on equipment that doesn't work well together or doesn't provide the power and autonomy you expected.
Wrong battery size
Too little capacity and your system may run out of energy sooner than expected. Too much capacity and you may spend money you didn't need to spend.
Wrong inverter or components
An undersized inverter or incompatible components can limit your system and force you to replace equipment later.
No plan for cloudy days
Without calculating autonomy, a system that works well on sunny days may struggle when solar production drops.
Size first. Buy second.
