About Total Power Supply

At Total Power Supply, we help homeowners, contractors, RV owners, off-grid users, and preparedness-minded buyers find practical power equipment for real-world needs.

Our catalog is built around the systems people rely on when power matters: solar panels, battery storage, inverters, generators, transfer switches, EV charging, wiring, protection, and backup-power accessories.

What We Focus On

Power equipment can be technical, expensive, and difficult to compare. We organize Total Power Supply around clear categories, accurate product information, and supplier-backed products so customers can make confident decisions.

• Solar and off-grid power: panels, kits, charge controllers, mounting, and accessories.
• Battery storage: lithium batteries, racks, cabinets, and supporting equipment.
• Inverters and charging: off-grid inverters, hybrid inverters, inverter chargers, and system components.
• Backup power: portable generators, home standby equipment, transfer switches, and emergency power products.
• Electrical essentials: wire, cable, connectors, disconnects, protection, distribution, and installation-support parts.

Why Customers Choose Total Power Supply

• Spec-driven shopping: We prioritize product details, compatibility context, and clear category organization over generic listings.
• Supplier-backed products: We focus on products from known manufacturers, distributors, and supplier partners.
• Practical fulfillment options: Some products ship parcel, some ship freight, and some use supplier-calculated rates. We keep shipping expectations visible wherever possible.

Built for Projects That Need Reliable Power

Whether you are preparing for outages, building an off-grid system, upgrading an RV or van setup, sourcing solar equipment, or comparing backup-power options, our goal is to make the buying process clearer and more dependable.

For system design, permitting, code compliance, and installation, we recommend working with a qualified electrician or installer. For product questions, order support, and availability, contact us and we will help point you in the right direction.
