Solar Homelabs covers solar power for equipment that runs around the clock, with a growing focus on battery and charge-controller troubleshooting. Start with solar batteries not charging if a working system stops accepting charge. That guide follows controller readings, battery protection states, charge profiles and wiring checks, with manufacturer documentation listed as sources.
For planning an installation, sizing an off-grid solar system for always-on homelab loads connects the load estimate to battery storage, panel output and inverter selection. The panel-count guide explains its array assumptions, while the MPPT vs PWM comparison covers controller choice and battery compatibility. The split-phase inverter guide addresses whether the intended loads need that output arrangement.
Use these articles alongside the manuals for your exact battery, controller and inverter. Each guide lists its sources so you can check the basis for a calculation or configuration choice. The solar battery bank calculator provides an estimate from your inputs and states its assumptions. Browse the articles below for the full guides, or use topics to find related coverage.

Split-Phase Inverter for an Off-Grid Homelab
This guide explains when an off-grid homelab needs a split-phase inverter, compares three 120/240 V options, and covers idle draw and panel wiring.
