If you already have an off-grid system and something is not working correctly, you do not need to start over. Have the inverter, charge-controller and battery model numbers available along with fault messages and a description of what the system is doing. Doug can help identify the next useful troubleshooting step and determine what equipment or parts may be needed.
Start with the system you actually have.
For an existing system, have your equipment model numbers, battery information and fault messages ready. For a new system, start with your location and the electrical loads you need to operate.
