MPPT Output Current Worksheet
MPPT Output Current Worksheet
Estimate battery side controller current from an array power allowance.
MPPT output current is a battery side check. It is different from the PV input voltage and current limits.
Enter the array power allowance and charging voltage, then compare the estimated output current with the controller rating.
How to use MPPT Output Current Worksheet
- Enter array rated power, conversion efficiency and current allowance.
- Enter battery charging voltage and controller output current rating.
- Select Calculate result. Read the returned values alongside the assumptions below before copying, exporting or acting on the result.
Why choose this tool?
The separate output check helps identify which controller specification is being compared.
Before you use the result
This compares output current only. Independently verify PV Voc in cold conditions, input Isc, MPPT range, allowed array power and battery limits. Passing output current is not approval.
Questions about MPPT Output Current Worksheet
Does passing output current approve the PV array?
No. Cold Voc, input Isc, MPPT range, permitted array power and battery limits still require review.
What should I check before using MPPT Output Current Worksheet?
Check Array rated power, Conversion efficiency, Current allowance and Battery charging voltage. Use the exact units shown beside the controls and replace any example values with your own inputs.
