How to Maintain Your Solar Inverter and Battery for Maximum Life

Your inverter and battery are the powerhouse of your solar system. With a few easy habits, you can extend their lifespan, reduce failure risks, and get the most from your investment.

Why Solar Inverter and Battery Maintenance Matters

Your hybrid solar system is more than just tech—it’s an investment in energy independence. Regular monitoring and maintenance will:

• Extend lifespan (10–15+ years)

• Prevent unexpected failures

• Maximize energy efficiency

• Protect your solar investment

  A small weekly habit saves big on future repairs.

1. Monitor System Performance Weekly

Use your Elios app or dashboard t

o check:

• Input/output voltage

• Battery charging cycles

• Temperature

• Load percentage

• Any error codes or alerts

Set a reminder to check stats weekly or bi-weekly, especially when seasons change.

2. Visual Inspections: 5 Minutes a Month

Walk by your system and check:

• Dust or debris around fans and vents

• Loose or discolored wiring

• Unusual sounds (buzzing or clicking)

• Secure mounting brackets

A quick visual check prevents hidden damage.

3. Keep It Cool and Clean

Heat = shorter inverter life. Dirt = inefficient cooling.

Tips:

• Install in a shaded, ventilated space

• Clean vents monthly

• Avoid airtight enclosures

• In cold regions, keep it dry and insulated

Your inverter performs best in “room temperature” comfort zones.

4. Battery Bank Best Practices

Well-sized and balanced banks last longer:

• Design for 5+ days of load

• Use high-quality batteries (like Elios lithium or LFP)

• Avoid more than 3 parallel strings

• Keep all cables symmetrical in length

Proper sizing = fewer failures, more consistency.

5. Prevent Corrosion

Corrosion kills performance. Stop it before it starts.

Do this:

• Apply non-hardening sealant or petroleum jelly to all metal terminals

• Use heat-shrink tubing for open wire ends

• Rinse battery tops with baking soda water 2x/year

Tip: Keep batteries above a floor drain or water-safe base.

6. Keep Batteries Fully Charged

Avoid deep discharge at all costs.

• Bring to full charge every 3 weeks

• Don’t rely on LED indicators—use an amp-hour meter or hydrometer

• Run a generator if needed during low-sun periods

A partially charged battery is a slowly dying battery.

7. Update Firmware & Software Regularly

Check for updates every 3–6 months:

• Improves performance

• Fixes bugs

• Adds safety features

Use the Elios app for remote, over-the-air updates.

8. Get a Pro Check-Up Annually

DIY maintenance is great—but once a year, call a certified technician to:

• Run diagnostics

• Check aging components

• Recalibrate your settings

• Recommend upgrades

Warning Signs to Watch

• Frequent resets or shutdowns

• Battery not charging

• Higher than usual heat

• Error codes that won’t clear

Don’t ignore the signs—early action saves your system.
