    Use Solar After Sunset

    When your panels make more than your home needs, Load Shifter stores the extra energy instead of turning solar output down, and gives it back in the evening or at the times you set in the app.

    Modular towers

    Start Small, Grow to 4 kWh

    Each Battery Tower stores about 1 kWh. Start with one and add towers on extension bases until your Smart-Base holds 4 kWh.

    More than a home battery

    Backup and On the Go

    Take a tower off its base to charge it directly from a solar panel, use its USB ports, or run essentials like your fridge and internet from the off-grid inverter during an outage.

    Why Load Shifter

    More Than a Portable Power Station

    A portable power station stores energy, but it doesn’t know what your solar system or your home is doing. Load Shifter is part of your CraftStrom system: it charges from your surplus solar automatically and works with Load Guard and the app.

    FAQ

    Frequently Asked Questions

    Will it work with my outlet and circuit?

    Most homes use a standard outdoor or indoor outlet on a circuit without heavy loads. Load Guard watches your home’s use and turns output down to stay within the safe circuit limit. Run our 5-point outlet check before you buy.

    Will it save enough to be worth it?

    Tell us your bill and we’ll show three numbers: conservative, typical and best-case. Savings come from using the power at home during the day.

    Where can I put it?

    Anywhere with 4+ hours of direct sun near an outlet: balcony, fence, deck, porch, shed or yard. The kit finder asks about your spot and cable run.

    Will it run my house in an outage?

    Solar alone lowers your bill but doesn’t power your home when the grid is down. Add a battery kit to keep essentials like the fridge, lights and Wi-Fi running.

    Is it allowed where I live?

    Yes. CraftStrom works in all 50 states. Load Guard keeps every watt in your home, so nothing flows back to the grid.

    What happens to extra power?

    Your home uses solar first. If you’re making more than you use, Load Guard turns the panels down, or a battery stores it for later.

    What will I pay and when will it arrive?

    See your full price, shipping and delivery window before checkout. No surprise accessories.

    Can I take it with me?

    Yes. It unplugs and moves with you, and it works in all 50 states.

    Can I trust the equipment?

    UL-certified inverters, NEC compliant, tested by Lawrence Berkeley National Lab and NREL, with warranties of up to 20 years.

    What if I get stuck?

    Our Houston team can walk you through Load Guard setup or Wi-Fi by appointment, and our FAQ covers the rest. Call (832) 850-3832.

    What Our Customers Say

    ★★★★★

    “I’ve been interested in plug and play solar for a few years now and when Craftstrom came out with their system I was happy to purchase a 2000 watt set-up. No utility involvement, no permits required, just a DIY installation. I’m really pleased with how it turned out and the production we’re already getting.”

    Chris · CA

    ★★★★★

    “Overall it was very easy to install, and is a great “point of entry” system for anyone interested in solar. And yes, it works surprisingly well in snow thanks to the bifacial panels!”

    Dave · PA

    ★★★★★

    “Craftstrom makes clean energy cheap and easy. No permitting. No electricians. But note that some assembly is required! About as difficult/easy as an Ikea bookshelf. The app tells me how much I’m generating each day, from each of the panels. Easy peasy.”
