A: Because loads are higher or the battery was not fully charged.
Solution: Reduce night loads or ensure full charging during the day.
Q: Why do batteries not reach 100% charge?
A: Because of incorrect charge settings or imbalance.
Solution: Check inverter charge settings and balance the battery bank.
Q: Why does an inverter reboot often?
A: Because of unstable power or firmware issues.
Solution: Check power source stability and update firmware.
Q: Why do inverter screens freeze or glitch?
A: Because of software bugs or static interference.
Solution: Restart the inverter or perform a soft reset.
Q: Why does a fuse blow after replacing it?
A: Because the root fault wasn’t fixed.
Solution: Inspect for short circuits before replacing again.
Q: Why do some batteries not communicate with the inverter?
A: Because of mismatched communication settings or cables.
Solution: Check communication port and select the correct protocol.
Q: Why does the inverter not turn on after power loss?
A: Because of discharged batteries or tripped breakers.
Solution: Recharge the battery or reset the breaker.
Q: Why does the inverter show overvoltage?
A: Because the grid or solar voltage is above safe range.
Solution: Verify input voltage and adjust limits if needed.
Q: Why does the battery not discharge fully?
A: Because the inverter limits depth of discharge for protection.
Solution: Adjust settings only if recommended by manufacturer.
Q: Why do solar panels underperform in the afternoon?
A: Because of panel heating or partial shading.
Solution: Keep panels clean and ensure proper tilt angle.
Q: Why does a battery swell or bulge?
A: Because of overcharging or internal gas buildup.
Solution: Stop use immediately and replace the battery.
Q: Why does a system trip during rain?
A: Because moisture affects exposed wiring or terminals.
Solution: Check weatherproofing and seal outdoor components.
Q: Why do inverters take time to start after shutdown?
A: Because internal capacitors need to reset.
Solution: Wait a few minutes before restarting.
Q: Why does backup time reduce over months?
A: Because battery capacity naturally degrades over time.
Solution: Do regular maintenance and replace old batteries.
Q: Why does an inverter run without load?
A: Because of internal self-consumption for standby functions.
Solution: Turn it off when not in use to save energy.
Q: Why do batteries not charge evenly in parallel?
A: Because of imbalance in voltage or internal resistance.
Solution: Balance the batteries and use equal cable lengths.
Q: Why does the inverter beep continuously?
A: Because it’s warning about overload or low battery.
Solution: Check load and battery status immediately.
Q: Why do inverters overheat faster in small rooms?
A: Because poor airflow traps heat around the unit.
Solution: Improve ventilation and keep space around inverter clear.
Q: Why do solar panels stop producing power suddenly?
A: Because of a disconnected string or damaged MC4 connector.
Solution: Inspect all panel connections and fix any breaks.
Q: Why does a new system not reach full output?
A: Because all components are still calibrating to each other.
Solution: Allow full charge-discharge cycles to stabilize performance.
Q: Why does the inverter go offline randomly?
A: Because of unstable Wi-Fi or monitoring connection.
Solution: Check internet connection and signal strength.
Q: Why does the battery voltage drop quickly under load?
A: Because of weak cells or high internal resistance.
Solution: Test each cell and replace any weak ones.
Q: Why do fuses blow when switching from grid to solar?
A: Because of sudden surge current during transfer.
Solution: Use a slower transfer mode or soft start function.
Q: Why do systems shut down at night unexpectedly?
A: Because the battery is empty or inverter sleep mode activates.
Solution: Check charge levels and disable unnecessary sleep settings.
Q: Why do inverter lights blink continuously?
A: Because the inverter is signaling a warning or event code.
Solution: Check the code meaning and address the issue.
Q: Why do batteries smell or leak?
A: Because of internal damage or overcharging.
Solution: Stop using immediately and replace safely.
Q: Why does battery performance drop during winter?
A: Because cold temperatures slow the chemical reaction.
Solution: Keep batteries in a moderate indoor environment.
Q: Why does solar charging stop midday?
A: Because the controller limits charging once voltage is high.
Solution: Allow the system to manage charge automatically.
Q: Why do breakers trip when solar and grid run together?
A: Because of backfeed or neutral current imbalance.
Solution: Verify wiring and isolate grid and solar neutrals.
Q: Why does inverter efficiency drop with age?
A: Because internal components wear out over time.
Solution: Do annual maintenance and replace aging parts.
Q: Why do systems show negative power readings?
A: Because current sensors are reversed or miss wired.
Solution: Correct the polarity of CT or current cables.
Q: Why do batteries not wake up from sleep mode?
A: Because voltage is too low for BMS to activate.
Solution: Use a charger to wake up the battery manually.
Q: Why do inverters make a ticking sound at startup?
A: Because relays are engaging internal circuits.
Solution: Let the inverter complete its startup process.
Q: Why do some batteries never show full bars on the display?
A: Because calibration is slightly off or voltage sensors differ.
Solution: Allow a full charge cycle to reset display accuracy.
Q: Why does inverter output fluctuate during cloudy periods?
A: Because solar input changes rapidly with sunlight levels.
Solution: Use batteries to smooth out the power delivery.
Q: Why does the system not save settings after reboot?
A: Because of a firmware glitch or power interruption.
Solution: Reconfigure settings and save before shutdown.
Q: Why do inverters refuse to sync with the grid?
A: Because frequency or voltage is outside the safe range.
Solution: Wait for stable grid conditions or adjust limits.
