Off-grid power planner
Turn a power idea into a specification you can verify.
Classify the load, test baseline and pressure conditions, then verify battery, solar, inverter, startup, and charging boundaries before comparing equipment.
Start from a real use case
Choose the constraint that sounds like yours.
Weekend RV
Plan a weekend RV power system
A practical baseline for a 12V fridge, lighting, charging, and a little laptop time.
Open baseline →Remote-work van
Plan a remote-work van power system
Start with connectivity, laptop charging, refrigeration, lighting, and reserve for weather variability.
Open baseline →CPAP overnight
Plan reliable overnight CPAP power
Separate critical overnight energy from optional daytime loads before choosing a battery class.
Open baseline →Small cabin
Plan a small cabin off-grid system
A conservative starting point for refrigeration, lights, device charging, a pump, and intermittent kitchen loads.
Open baseline →After the number
Make the next decision clearer.
A useful result identifies the next specification to verify before you narrow the component shortlist.
Start here
Separate daily energy from peak power
Battery capacity answers a different question from inverter output. Plan both before comparing hardware.
Storage
Understand usable battery kWh before Ah
Amp-hours only become meaningful after you choose voltage and usable depth of discharge.
Generation
Plan solar production by month, not one annual sun number
A system that looks sufficient on an annual average can still be constrained by season, shade, orientation, and weather.
AC loads
Plan an inverter around the loads that overlap
The right question is not what inverter size is popular, but what must run at the same time and what starts under load.
Architecture choices
Compare paths before comparing products.
Architecture choice
Portable power station or DIY battery system?
Choose based on portability, expandability, integration effort, and the exact loads you need to support.
Voltage choice
12V or 24V for a small off-grid system?
Voltage is an architecture decision driven by power level, current, existing loads, and future expansion.
