How this service works
Battery capacity, inverter size, amp-hours, runtime and solar recharge for a list of loads
Output
Returns a JSON object with recommended battery capacity in kWh and amp-hours, suggested inverter size in watts, estimated runtime given the loads, and solar panel/recharge requirements based on peak sun hours — all sized to the specified loads, battery chemistry, autonomy days, and system voltage.
Example use cases
Off-grid cabin power sizing
“I'm setting up a small off-grid cabin and need to know what size LiFePO4 battery and inverter I need. My loads are a fridge at 150 watts running 10 hours a day, LED lights at 40 watts for 6 hours, and a laptop at 60 watts for 4 hours. I want 3 days of autonomy and get about 5 peak sun hours. System voltage should be 24V.”
RV solar battery planning
“Help me size the battery and solar setup for my RV. I have an AC unit (surge 2000W, running 600W for 4 hours), a TV at 80W for 3 hours, and a water pump at 60W for 1 hour per day. I'd like 1 day of autonomy, lithium-ion chemistry, 12V system, and I average about 6 peak sun hours.”
Checking runtime on existing battery
“I already have a 5 kWh battery and want to know how long it will last with these loads: Fridge:150:8|Router:12:24|LED lights:40:4. Can you run the battery backup calculation using that existing battery capacity so I can see the runtime estimate?”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/energy/battery-backup?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, structured calculation for sizing a battery backup or off-grid solar system from a list of electrical loads. It handles multiple load types including motor surge loads, multiple battery chemistries, and solar recharge estimation in one call — ideal for agents automating energy planning, off-grid system design, or RV/cabin power audits. Prefer this over generic energy calculators when you need LiFePO4/AGM chemistry-aware sizing with autonomy-day and sun-hour inputs in a single API call.
Side effects
- Missing required 'loads' parameter returns an error
- Malformed loads string (wrong delimiter or missing fields) may cause a parse error
- More than 30 loads specified exceeds the stated maximum
- Invalid battery chemistry value outside accepted options (lifepo4, lithium_ion, agm, flooded)
- Invalid system_voltage value outside 12/24/48 returns an error
- Extremely high surge wattage combinations may produce warnings or edge-case results
