Check the numbers yourself
Three concept-stage checks we run on every project. Change the inputs and the working updates line by line. When the answer matters, ask us for a full review.
Battery storage
Energy at the grid, and when it runs short
How much of a battery's nameplate energy reaches the meter, and how many years until fade takes it below the contract.
Energy yield
P90 from an uncertainty budget
Lenders size debt on P90. Enter the expected yield and each uncertainty; they combine by root-sum-square.
Process loads
Voltage dip from a motor start
Will your largest motor trip the plant when it starts on inverters or a weak grid?
On the grid, ask your utility for the fault level; 50–250 MVA at 11 kV is common. On inverters alone, use about 1.5 × the inverter MVA rating.
These are concept-stage estimates for screening, not a substitute for a design study. For a full check on your own project, get in touch. Results stay in your browser; nothing you enter is sent to us.
