I understand that you are encountering an error while compiling a Simscape network for your model, specifically related to the "PS Lookup Table (1D)1" block in the "Model/SOLAR PV/Electrolyzer" subsystem.

It is required that all branches of a conditional expression must have consistent types (including size and unit) in the Simscape language. The compiler translates all branches regardless of being active or not. The equations defined inside a conditional section are not subject to this constraint, for example:

component getT
    inputs
    T = 0;
    end
    outputs
    y = zeros(size(table_T&#39;));
    end
    parameters
    table_T = [1 2 3 4]&#39;;
    table_val = [1 2 3 4]&#39;;
    end
    parameters(Access=private)
    N = size(table_val,2);
    end
    % equations declared inside a conditional section are not subject to this constraint.
    %  In this case, only the active branch will be inclused in the system.
    if N==1
        equations
        y == tablelookup(table_T, table_val, T, interpolation = linear, extrapolation = nearest);
        end
    else
        equations
        assert(ndims(table_val)==2);
        y == tablelookup(table_T,1:N,table_val,ones(1,N)*T,1:N, interpolation = linear, extrapolation =
        nearest);
        end
    end
end

component MyComp
    inputs
    T = 0;
    end
    outputs
    y = zeros(size(table_T&#39;));
    end
    parameters
    table_T = [1 2 3 4]&#39;;
    table_val = [1:4; 5:8; 9:12; 13:16];
    end
    components(ExternalAccess=observe)
    getT = getT(table_T=table_T, table_val=table_val);
    end
    equations
    T == getT.T;
    y == getT.y;
    end
end
