Battery Storage for Off-Grid Solar Systems
Reliable Power, Anytime, Anywhere
​
In an off-grid solar installation, battery storage is essential. It allows you to store the energy generated by your solar panels during the day for use at night or during cloudy periods—ensuring a consistent and reliable power supply, even when the sun isn't shining.
​
Why Battery Storage Matters
Off-grid systems are not connected to the utility grid, so energy independence relies entirely on how well your solar and storage system is designed. A high-quality battery storage solution helps to:
· Provide consistent power 24/7 · Improve energy security in remote or rural areas · Reduce reliance on diesel generators, lowering fuel costs and emissions
· Support critical loads such as refrigeration, lighting, communications, and appliances

Inverters
​
Victron makes several types of inverters and inverter/chargers. The most commonly used are:
Victron Phoenix Inverters
Type: Pure sine wave inverter
Basic off-grid systems where AC charging isn't needed. Converts DC (12V/24V/48V) to clean AC power. Highly efficient and stable for sensitive electronics. Remote on/off support. Optional VE.Direct communication for monitoring. Sizes range from 250 VA to 5000 VA. Best for: Small off-grid cabins, campers, boats
Victron MultiPlus Inverter/Chargers
Inverter + AC charger + automatic transfer switch. Off-grid or backup systems with generator/grid input. Inverts DC to AC, and charges batteries from generator/grid when needed. Seamless switching between power sources (AC input, batteries, generator) Power Assist feature: boosts limited generator/grid input with battery power. Remote monitoring and programming via Victron GX systems or VictronConnect
Available in various power capacities (800 VA to 5 kVA+) Best for: Off-grid homes, tiny houses, solar backup systems
​
Victron Quattro Inverter/Chargers
Advanced inverter/charger with dual AC inputs (e.g., grid + generator). Complex off-grid and hybrid setups. Everything the MultiPlus does, plus:. Two AC inputs with auto-switching (e.g., grid + generator). Ideal for larger installations and full off-grid homes. Load prioritization, generator auto-start support. Available up to 15 kVA. Best for : Large off-grid homes, commercial setups, microgrids
Monitoring & Control Options
All Victron inverters can be integrated into a full Victron GX system for advanced monitoring:
Cerbo GX + Touch screen. VictronConnect app (via Bluetooth). Remote monitoring via Victron VRM portal
