Why Choose The Light Group USA for Battery Retrofits
Adding a battery to an existing solar system is not the same as installing new solar.
We Work on Systems Other Companies Installed
Many battery companies focus only on:
New solar installations
Pre-packaged systems
Simple add-ons
We specialize in:
Retrofitting existing systems
Upgrading aging inverters
Reworking electrical configurations
Integrating storage into older designs
If your system was installed 3–10 years ago, retrofit complexity increases.
Battery retrofits require engineering — not just installation.
Battery Strategy Depends on Texas Market Conditions
Texas is unique:
No mandated retail net metering
Buyback programs vary by provider
Peak pricing exposure
Free nights plans
ERCOT grid events
We evaluate:
Your current retail plan
Export credit structure
Peak pricing window
Import vs export balance
Battery sizing without rate analysis is incomplete.
Hardware alone does not fix strategy.
Battery Compatibility Is Not Universal
Before installation, we evaluate:
Inverter model and age
Electrical panel configuration
Breaker capacity
Roof penetration integrity
Monitoring platform
Load management requirements
Some retrofits require:
Inverter replacement
Critical loads panel
Hybrid inverter upgrade
Additional control equipment
We do not guess compatibility.
We design for performance.
Professional Electrical Integration Matters
Battery retrofits involve:
High-voltage integration
Load balancing
Transfer switching
Permit compliance
Utility coordination
Improper installation can cause:
System faults
Reduced efficiency
Warranty issues
Safety risks
Every installation is:
Permitted
Inspected
Tested
Commissioned properly
Many Homeowners Call Us After Problems Appear

Inverter upgrades
Storage expansions
Electrical adjustments
System diagnostics
