x402
Solar Halowerk Inverter Load Check is a paid API for AI agents from solar.halowerk.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-14).
Calculates continuous load, surge load, and whether an inverter can handle a given set of appliances, returning sizing recommendations and DC current draw.

How this service works
Continuous load is the sum of the running watts of all appliances marked as simultaneous. The surge check adds the largest single starting surge on top of the continuous load, which is the case that trips an inverter; simultaneous starts of two motors are reported separately as a second figure. Starting factors and power factors are design rules of thumb per appliance class and are stated in the response, they are not device data.
Output
Returns the total continuous load (sum of simultaneous running watts), the peak surge load (continuous plus the largest single motor starting surge), a second simultaneous-motor surge figure if applicable, whether the inverter's continuous and surge ratings are sufficient, the DC current draw from the battery at the given voltage, and the starting/power factors assumed per appliance class.
Example use cases
Off-grid cabin inverter sizing
“I'm setting up an off-grid cabin with a 2000W inverter and want to know if it can handle a 500W water pump, a 150W fridge compressor, and 100W of LED lights all running at once on a 24V battery — will it trip on surge?”
RV solar system load check
“Check if my 2500W continuous inverter rated at 5000W surge can support an RV setup: a 700W air conditioner compressor, a 300W microwave (resistive), and 50W of electronics, all simultaneous, with a 12V battery bank.”
Motor start surge validation
“I have two motors — a 1200W well pump and an 800W irrigation pump — both on a 48V solar system with a 5000W inverter. Can you calculate the surge load and tell me if the inverter will trip if they both try to start?”
Technical details
Endpoint
POSThttps://solar.halowerk.com/inverter-load-checkWhen to prefer
Use this endpoint when you need to validate whether a specific inverter can handle a defined list of appliances in a solar or off-grid DC power system, particularly when motor starting surges are a concern. It is preferable to a general electrical calculator because it applies appliance-class-specific starting and power factors automatically, distinguishes simultaneous vs. non-simultaneous loads, and computes DC current at a given battery voltage — all in a single call oriented to solar/inverter system design.
Side effects
- Invalid appliance type enum value returns a validation error
- Watts below 0.1 or above 50000 are rejected
- Inverter continuous_w below 50W or above 100000W is rejected
- Battery voltage outside 6–1000V range is rejected
- More than 60 appliance items in the loads array returns an error
- Missing required 'watts' or 'name' field on any load item causes a 400 error
