9 tools, as the server itself reported during our check on Oct 31, 2026.

• generate_wiring_diagramGenerate an electrical wiring diagram for campers, boats, or off-grid setups. Returns the schematic as an image (batteries, chargers, protection components, loads) and a link that opens it in the VoltPlan editor to refin
• list_component_typesList all available component types and example configurations for building wiring diagrams. Use this to understand what parameters are needed before calling generate_wiring_diagram.
• calculate_wire_gaugeCalculate the recommended wire gauge / cable cross-section for a DC circuit. Considers both ampacity (current carrying capacity) and voltage drop to recommend the optimal cable size. Also returns total resistance, power
• calculate_power_budgetCalculate total daily energy consumption from a list of electrical loads. Each load specifies its power draw, how many hours per day it runs, and quantity. Returns total daily energy (Wh and Ah), peak power draw, and ave
• calculate_battery_bankCalculate the recommended battery bank size based on daily energy consumption. Accounts for days of autonomy (how many days without charging) and depth of discharge. Returns required capacity, number of batteries, and wi
• calculate_solar_sizeCalculate the required solar panel wattage to cover daily energy consumption. Accounts for peak sun hours at the location and system efficiency losses (MPPT conversion, wiring, temperature derating). Returns required wat
• calculate_charging_timeEstimate how long it takes to charge a battery bank from a given state of charge to a target level. Accounts for the bulk charging phase (constant current, up to ~80% SoC) and the slower absorption phase (tapering curren
• calculate_inverter_sizeCalculate the recommended inverter size for running AC loads from a DC battery system. Accounts for continuous power, startup surge power (motors typically surge 2-3x), and includes a 25% headroom for the continuous rati
• calculate_battery_configDetermine how to arrange batteries in series and/or parallel to achieve a target voltage and capacity. Returns the number of batteries needed, the wiring configuration (e.g. 2S3P), and step-by-step wiring instructions.
