Solar Batteries: Upfront Pricing and Options
Solar Batteries give you a reliable backup with less guessword. When the power goes out, a solar battery keeps the important stuff running. You’re not going to buy a Lambo with the savings, but what you will get is practical peace of mind.
Option 1
Tesla Powerwall
Starting Price: $19,250
If you want a home battery that works smarter, not harder, the Tesla Powerwall is the one. It hooks up to your solar or the grid, so you can ride through outages and shift power when rates are high, saving cash and keeping lights on.
A Powerwall 3 system with the Gateway starts at $19,250 for the first 13.5 kWh battery, with additional batteries priced at $12,500 each (stack up to 10).
The system plays nice with your exisiting solar setup, and the app gives you hands‑on control. Built tough, backed by Tesla reliability, and ready for Idaho winters (up to –4°F).
With its integration with your Tesla EV, control when and how your EV charges (day, night, or during outages) using stored solar energy.
Share your EV’s battery with your home for extra backup support.

Rocky Mountain Power SolarEdge Rebate
Rocky Mountain Power’s Wattsmart® Battery Program helps lower the cost of installing a qualifying battery, like the SolarEdge system we offer.
Because we’re part of the program, you’ll see reduced up-front pricing without any rebate forms or extra steps on your end. Homeowners who are enrolled in the Wattsmart® Battery Program will also receive ongoing bill credits.
Rocky Mountain Power offers you $400/kilowatt with a cap of $2,000.
The utility may occasionally use a portion of your battery during high-demand times, but a reserve is always kept for backup power at home.
Option 3
EG4 Home Solar Battery
Starting Price: $16,250
If you’re looking for a flexible battery that plays well with different setups, EG4 is a solid choice. It’s not locked into one brand of inverter, so you’ve got more freedom to build a system that fits your home.
An EG4 system with a 14.3 kWh battery and 18k hybrid inverter starts at $16,250 for the first battery, with additional batteries priced at $8,000 each, up to 3 total. Grid Boss and Flex Boss configurations start at $19,575, with additional batteries available for $8,500 each, up to 5.
With lithium iron phosphate chemistry and models up to 14.3 kWh, EG4 batteries are built for long life and steady performance, even when temps dip below freezing. Reliable, expandable, and ready for Idaho.

Self-heating tech and a wide temperature range keep your battery reliable, even when it’s freezing outside.
You Don’t Need a Solar Battery. But You Might Want One.
Not every Idaho home needs a solar battery. If your main goal is backup power for outages or using more of the solar energy you already generate, a battery could be a solid choice. We install three kinds: Tesla Powerwall (premium choice + compatible with Tesla EV), SolarEdge (works with SolarEdge systems), and EG4 (more flexible and great for larger or off-grid setups).
What Can a Solar Battery Actually Do?
Keep your fridge, lights, and essentials running when the grid goes down
Let you use more of your solar power at night or during peak rate hours
Add a layer of energy independence. Great for rural or off-grid spots
Here’s what a battery won’t do:
Wipe out your entire energy bill
Power your whole house during an outage (unless you go big)
Make you invincible during Idaho winters, just more prepared
Not Sure What You Need?
You’re not alone. That’s why we start every job by asking questions, checking your setup, and being real with you. If a battery makes sense, we’ll tell you why. If it doesn’t, we’ll tell you that too. And if you already have solar and just want to explore backup options, we’ll take a look and help you plan it out.

FAQ
How much does a solar battery system cost in Idaho?
In Idaho, a solar battery typically costs $16,000–$20,000 installed for the first battery, depending on the system you choose. Additional batteries cost less per unit.
Here’s what that looks like in real numbers:
EG4 (14.3 kWh + 18k hybrid inverter): $16,250 for the first battery; $8,000 per additional battery
EG4 Grid Boss / Flex Boss: $19,575 upfront; $8,500 per additional battery (up to 5).
SolarEdge (10 kWh + Home Hub): $18,500 for the first battery; $11,500 per additional battery. Qualifies for the Rocky Mountain Power Wattsmart program. Rocky Mountain Power offers you $400/kilowatt with a cap of $2,000 when enrolled.
Tesla Powerwall 3 (13.5 kWh + Gateway): $19,250 for the first battery; $12,500 per additional battery (up to 10).
Are there rebates or incentives for solar batteries in Idaho?
Yes! Rocky Mountain Power’s Wattsmart® Battery Program offers incentives for SolarEdge batteries—typically $400 per kW up to $2,000 upfront, plus $15 per kW annually—which can reduce your up‑front costs. We handle it all, so you don’t have to.
Can a solar battery keep the power on during Idaho outages?
Absolutely. Batteries like Tesla Powerwall, SolarEdge, EG4 can power essential circuits (lights, fridge, Wi‑Fi) during outages. With proper sizing, they can even offset energy usage overnight. We’ll design it for your needs.
How long do solar batteries last in Idaho’s climate?
Modern lithium‑ion batteries typically last 10–15 years (some up to 7,000+ cycles). EG4’s LiFePO₄ chemistry handles wide temperature ranges—including freezing winters.
Will the battery work with my current system?
Yes! Since we install Tesla Powerwall, SolarEdge, and EG4 systems, we can match or retrofit your setup. If your system isn’t battery-ready, we can let you know what it’ll take—no jumping through hoops.
