Every guide is backed by certified engineering spec sheets, KaTeX mathematical proofs, and real-world off-grid analysis.
Authoritative engineering investigation into solar inverter Total Harmonic Distortion (THD). We analyze Fourier series harmonic spectra, odd-order negative sequence motor braking, parasitic iron core heating, and active LC line reactor filtering.
Authoritative engineering investigation into Potential-Induced Degradation (PID) in high-voltage photovoltaic strings. We analyze sodium ion drift electrochemistry, EVA encapsulant leakage currents, electroluminescence shunting diagnostics, and nighttime high-voltage reverse-bias recovery circuits.
Engineering analysis of solar DC disconnects and breakers. We model magnetic blowout deflection physics, polarized breaker reverse-current fire hazards, and arc chute splitting.
Engineering analysis of solar microgrid black start restoration. We cover grid-forming voltage sources vs grid-following current sources, transformer inrush saturation, and droop paralleling.
Engineering guide to local, zero-cloud solar inverter telemetry. We cover RS485 differential signaling, 120-ohm bus termination, Modbus register decoding, and Home Assistant automation.
Engineering analysis of inverter tare loss and idle consumption. We model magnetizing core losses, low-load efficiency collapse, why search mode fails, and dual-inverter day/night staging.
Engineering analysis of solar battery equalization. We break down lead-acid sulfation reversal, why equalizing LiFePO4 causes catastrophic destruction, top-balancing physics, and inverter configuration.
Authoritative engineering analysis of direct current (DC) arc faults in photovoltaic arrays. We examine plasma physics, cross-mating MC4 connector failures, UL 1699B DSP detection algorithms, and nuisance trip mitigation.
Engineering guide to running Level 2 AC electric vehicle chargers on off-grid solar. We model J1772 pilot signal modulation (6A to 48A), CT clamp solar following, and battery SOC interlocks.
