[TRNSYS-users] Error message 441 after create a own type

Hi, my name is Luis! I’m trying to develop an energy controller system.
This controller works based on the excess or demand of energy. When there
is an excess, the controller sends energy to an electrolyzer (Type 160) and
an inverter/regulator (Type 48B) connected to batteries (Type 47B).

In cases where there is energy demand (this demand comes from a load, Type
14H), the controller draws energy from a PEMFC (Type 173) and the batteries
(Type 47B).

When I run this simulation, I encounter *Error 441*, which states: *"The
inputs to the listed units have not converged at this timestep. The values
from the last iteration will be used, and the simulation will proceed."* As
a result, *Error 450* appears: *"The maximum number of warnings allowed per
simulation has been exceeded. Please fix these warnings or increase the
limit on the number of warnings allowed per simulation."*

 Can anyone help me with this problem?

Thank you so much in advance,

Greetings,
Luis Angel Chire
