Every guide is backed by certified engineering spec sheets, KaTeX mathematical proofs, and real-world off-grid analysis.
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.
Authoritative engineering guide to AC-coupling grid-tied solar microinverters to off-grid battery systems. We analyze frequency shifting modulation (Rule 21), the 1.0x ratio rule, and DC bus overvoltage defense.
Engineering comparison between induction cooktops and propane ranges for off-grid homes. We benchmark thermal transfer efficiency (85% vs 35%), daily kilowatt-hour consumption, and inverter surge requirements.
Engineering guide to running heavy cyclone dust collectors and woodworking machinery on off-grid solar. We calculate motor starting LRA surges, VFD ramp-up power curves, and 48V battery discharge C-rates.
