Pecron E3800LFP Runtime Calculator
Use this source-linked record to estimate runtime from tracked capacity, output, charging, and weight fields. Unknown specs stay unknown until an official or manufacturer-grade source confirms them.

Surge output stays unknown because the checked official source publishes a 4200W bidirectional inverter rating without a separate peak value, unlike the sibling E3600LFP whose page states a 7000W surge. Solar input stores the published 3000W total across the two 1500W XT60 inputs. DC output uses the listed XT60 12V/30A port; the front-panel car socket is the lower 12V/10A path.
Runtime Starting Points
These are formula estimates using the tracked capacity, a 10% reserve, and each scenario's default wattage and duty cycle. They are planning starters, not measured runtimes.

Good fit when
- Capacity is in a larger outage/RV class, so the useful question is usually output limits, recharge speed, and weight rather than watt-hours alone.
- Tracked AC output is high enough for many household plug-in loads, but surge still needs a separate check.
- USB-C output is tracked at laptop-class power, useful for direct DC charging when the device supports it.
- Tracked solar input is 3,000 W before panel, weather, angle, and controller losses.
Watch out for
- Surge output is unknown, so do not assume compressor, pump, or power-tool startup will work.
- Still unknown in the source-backed record: surge output.
- Tracked weight is in a heavier class; plan where it will live before treating it as a grab-and-go station.
- Confidence is not marked verified; keep the linked source context visible before making a purchase or emergency plan.
