Ohm's law, temperature coefficients, Peukert's law, cable ampacity — the non-negotiable math.

Chemistry-specific depth of discharge, parallel constraints, BMS coordination, temperature derating.

Series vs parallel vs SP, cold Voc calculations, MPPT window validation, array mixing.

Dual DC-DC/MPPT combos, inverter-chargers, 3-in-1s, multi-voltage auto-detection.

Multi-source coordination, combined charge current limits, smart alternator interaction.

Australia 120V DC, NEC Article 551, AS/NZS standards — region-specific hard limits.

Real-world topologies submitted by installers: solar blankets, dual controllers, SP banks, pre-built rigs.
