Solar Inverters

Off-Grid Solar Inverters and 48V Inverter Chargers

An off-grid solar inverter is the heart of any battery-based solar system. It converts the DC power stored in your batteries into the clean 120V or 240V AC power your home, cabin, or RV runs on, so you get grid-quality electricity with no grid connection at all. We stock off-grid, hybrid, and inverter/charger models from trusted brands including SunGold Power, Rich Solar, LuxPower, EcoFlow, and Victron.

Off-Grid Solar Power Inverters for Home and Cabin

A dedicated off-grid solar power inverter is built to run entirely from your battery bank and solar array, with no utility feed required. That independence is the whole point: when the grid goes down, your power stays on. Larger split-phase units can carry a full home’s essentials, while compact models are perfect for a cabin, workshop, or van.

48V Inverter Chargers and All-in-One Units

A 48V inverter charger combines the inverter, a solar charge controller, and a battery charger in a single box. Running your system at 48V instead of 12V or 24V means lower current, thinner cable runs, and less energy lost as heat, so more of your solar harvest actually reaches your appliances. These all-in-one units cut wiring, save wall space, and simplify installation.

Pure Sine Wave Inverters for Sensitive Electronics

Pure sine wave inverters produce smooth, utility-grade AC power. That clean output matters for anything sensitive: variable-speed well pumps, medical devices, computers, and modern appliances all run cooler and quieter on a pure sine wave 48V inverter than on a cheaper modified-wave unit. If it plugs into a wall at home, a pure sine wave inverter will run it right.

48V Split Phase Inverters for 120V/240V Loads

A 48V split phase inverter delivers both 120V and 240V from one unit, which is exactly what a whole home needs. That lets you run a deep well pump, a central AC, a dryer, or an EV charger straight from your off-grid system, no separate transformer required. Many split-phase models also stack in parallel, so you can add capacity as your loads grow.

Hybrid vs. Off-Grid: Choosing the Right Inverter

A pure off-grid inverter runs from batteries and solar only. A hybrid inverter adds grid-tie and battery-backup modes, so it can sell power back or ride through outages while still connected. If you have utility service and want backup plus savings, browse our hybrid inverters; if you are fully off the grid, the off-grid models here are built for you.
