Keep the Lights On — Even When the Grid Goes Down

Power outages in Northern California aren’t just inconvenient — they’re becoming a regular part of life. At Menderix, we install battery storage systems that help you stay powered during blackouts, save money on energy bills, and get more value from your solar investment.

Whether you’re dealing with PG&E shutoffs, SMUD peak-time pricing, or just want more control — our battery systems give you peace of mind and energy independence.

Why Homeowners in Sacramento Add Battery Storage

  • Protection from Outages. Wildfire season. Storms. Grid failures. A backup battery keeps your home running when others go dark — powering lights, appliances, internet, and even HVAC.
  • More Value from Your Solar. With NEM 3.0, exporting unused solar power to the grid is worth less than ever. A battery lets you store your excess energy and use it when it’s most valuable — like in the evening or during outages.
  • Lower Utility Bills with Smart Timing. Avoid expensive peak-time rates by using stored power when electricity is most expensive — especially for SMUD Time-of-Day or PG&E EV rate plans.
  • Custom Systems for Your Home. From compact setups to whole-home backup, we size your system based on what you care about most — fridge? HVAC? Medical equipment? You choose what stays on.

What We Install

We work with the most trusted brands in home battery storage such as:

  • Tesla Powerwall
  • Enphase IQ Battery
  • Sol-Ark hybrid inverters
  • FranklinWH
  • SolarEdge Energy Bank

All systems are eligible for California’s SGIP rebate program and can be added to new or existing solar installations.

Our Process

Whether you already have solar or are starting fresh, we handle every step:

  • Site evaluation and energy usage review
  • System design tailored to your home and needs
  • Rebates and SGIP paperwork
  • Permit approvals and utility interconnection
  • Professional installation by licensed technicians
  • Activation and customer walkthrough
  • Optional system monitoring plans for performance and status alerts

We don’t just install — we deliver a complete, reliable backup solution.

Is Battery Backup Worth It?

If you’ve asked yourself:

  • “What happens during the next PSPS shutdown?”
  • “Why am I exporting power for pennies when I could use it later?”
  • “Can I keep my fridge, Wi-Fi, or CPAP on during an outage?”

…then yes — it’s probably time to consider battery storage.

Frequently Asked Questions

How long will my battery last during a power outage?

It depends on the size of your system and what you power. A standard battery like the Tesla Powerwall can typically run essentials (like your fridge, lights, Wi-Fi, and some outlets) for 8–12 hours, or even longer with solar recharging.

Can I power my whole home with a battery?

Yes — but it depends on your energy usage and how many batteries you install. Most Sacramento homeowners choose to back up critical loads (e.g., fridge, lighting, internet, medical devices) rather than the entire house to maximize cost efficiency.

Will battery storage help me save money on my electric bill?

Yes. Batteries can shift your energy usage away from expensive Time-of-Use (TOU) evening hours. That means less reliance on PG&E or SMUD during peak pricing — and more use of your own stored solar energy.

What are the best battery brands available?

We install trusted, Tier 1 battery systems — including Tesla Powerwall, Enphase IQ Battery, SolarEdge Home Battery, FranklinWH, and low-voltage lithium batteries approved for use with Sol-Ark inverters. All systems are compatible with local utilities like SMUD, PG&E, and Roseville Electric, ensuring smooth interconnection, backup reliability, and long-term performance.

Is battery storage eligible for California incentives?

Yes! The Self-Generation Incentive Program (SGIP) offers rebates for eligible homeowners — especially those in high fire-threat zones or with medical needs. We’ll help you check your eligibility and handle the paperwork.

Do I need solar panels to use a battery?

Not necessarily — batteries can be installed as standalone backup systems. However, they work best (and save you the most) when paired with solar, since you can charge them daily with free energy from the sun.

What happens when the battery is fully charged?

Once your battery is fully charged, any excess solar energy can either be used immediately to power your home, sent back to the grid (if you’re on a NEM plan), or curtailed if you have a zero-export system. Meanwhile, your battery will continue supplying stored energy during peak demand or outages, maximizing your energy independence and savings. We design every system to minimize waste and make the most of every kilowatt produced.

Can I monitor my battery system?

Absolutely. All systems we install come with mobile apps — like the Tesla app or Enphase Enlighten — that let you track performance, see charge levels, and get alerts in real-time.

What if something goes wrong with the battery?

You can always reach out to Menderix for fast local support. We also offer optional performance monitoring, where we keep an eye on your system and alert you if there’s an issue — so you don’t have to worry.

How much does battery storage cost in Sacramento?

Costs vary depending on brand, size, and setup — but most systems range from $9,000 to $18,000 before incentives. We’ll give you an honest quote and help you find rebates and financing options that fit your budget.
