Engineering comes first
This website explains system concepts; it is not a code-compliant design package. A complete project needs electrical design, plumbing diagrams, structural plans, control sequences, sanitation strategy, applicable certifications, and commissioning procedures.
Professional review should cover
- DC voltage, current, disconnecting, overcurrent protection, arc and ground-fault behavior, conductor ratings, enclosures, and bonding.
- Tank pressure rating, relief devices, expansion, temperature limits, mixing valves, scald protection, and drainage.
- Legionella and other microbial risks, potable-water separation, materials compatibility, corrosion, and maintenance.
- PV structural attachment, wind and snow loads, roof or ground conditions, fire access, and local permitting.
