When your off-grid system isn't working, start with the problem.
SolarMan helps Big Island off-grid customers diagnose inverter faults, battery problems, charging issues, generator interaction and system-performance problems. Doug Mycko works with the equipment you already have and helps determine the next useful troubleshooting step.
Off-grid problems rarely happen in isolation.
A low battery can look like an inverter problem. A generator problem can look like a charging problem. A wiring or configuration issue can make good equipment behave badly. Troubleshooting means looking at the system as a whole instead of replacing parts at random.
Inverter faults & shutdowns
Unexpected shutdowns, overloads, low-voltage events, AC input problems, configuration issues and systems that will not produce the expected output.
Battery problems
Low state of charge, batteries that will not charge correctly, uneven battery behavior, lithium communication issues and battery banks that no longer support the expected loads.
Solar charging problems
Low PV production, charge controllers not reaching expected output, missing array power, charging-stage problems and solar that does not appear to be keeping up with the loads.
Generator charging
Generators that connect but do not charge correctly, charging that changes when PV is active, AC-input limits, generator compatibility and backup-power behavior.
OutBack system problems
Support for existing FX, Radian, FLEXmax, MATE and related OutBack equipment, including replacement boards, controls and system-level troubleshooting.
System performance
Systems that technically run but do not deliver the expected overnight capacity, load capability, solar recovery or generator run time.
Have a few details ready.
The fastest way to begin is with information from the actual system.
- Inverter make and exact model number
- Battery make, model and quantity
- Charge-controller make and model
- Any fault codes or warning messages
- What was running when the problem occurred
- Photos of the equipment and display screens when useful
- Whether the problem occurs on solar, generator, battery power or all three
SolarMan doesn't have to have sold it.
Many Big Island homes already have off-grid equipment installed. The first question is not who sold the system. The useful question is what the equipment is doing now.
SolarMan can help evaluate existing systems and identify practical next steps, including settings, testing, replacement components, battery upgrades and equipment changes when they are actually needed.
Talk with DougDiagnose before replacing equipment.
Identify the symptom
Start with exactly what happens: shutdown, fault, weak charging, low battery, missing solar, generator problem or insufficient power.
Look at the whole system
Check the relationship between PV, charge controllers, batteries, inverter, generator and loads instead of assuming the first component showing a warning is the cause.
Make the useful correction
That may mean changing a setting, correcting wiring, testing a component, replacing a failed board or planning an equipment upgrade.
Keeping existing off-grid systems running matters.
SolarMan stocks and sources replacement equipment and repair parts for off-grid systems, with particular experience around OutBack equipment and systems that have been operating for years. When an older system can be repaired sensibly, replacing the entire system may not be necessary.
Sometimes the repair reveals a sizing problem.
If the equipment is functioning but the system is consistently short on energy or power, the next step may be battery capacity, additional solar, inverter capacity or a broader system redesign.
Tell Doug what the system is doing.
Start with the equipment model numbers, any error messages and what was happening immediately before the problem. That gives the troubleshooting process a useful starting point.
