FAQ
Q1: Does it support grid-connected operation?
A1: Yes, it supports grid-connected operation. A grid-connected control system（ComAp/SmartGen） can be configured based on the customer's grid interface
Q2: Can biogas or shale gas be used?
A2: Custom versions for low-calorific-value fuels are available, but a gas composition report must be provided.
Q3: What are the advantages over diesel generators?
A3: Gas is cleaner, has lower operating costs, longer maintenance intervals, and produces less noise.
