Get the best of both worlds with Rocksolar's all-in-one hybrid inverters, built to handle grid-tie and off-grid operation in a single unit. Rather than choosing between staying connected to the utility grid or running fully independent, these inverters let you do both — drawing from solar and battery storage when needed, and seamlessly switching to grid power or backup when it isn't.
This collection features Growatt's 10kW split-phase hybrid inverter with an integrated UPS function for near-instant backup switching, alongside Sol-Ark's 15kW and 18kW all-in-one systems built for larger residential loads that demand more capacity and flexibility. Most models support Wi-Fi and app monitoring, MPPT solar charge control, and compatibility with both LiFePO4 and lead-acid battery banks.
Whether you're looking to add battery backup to an existing grid-tied system or want a single inverter that adapts to however you use power, these hybrid units are designed to combine reliability, efficiency, and smart home integration in one piece of equipment.

Common Question
Can a hybrid inverter work without a battery?
Most can run as an ordinary grid-tie inverter with no battery fitted, and have storage added later. You lose outage protection until the battery is installed — that is the whole reason to buy hybrid rather than grid-tie.
How much does a hybrid solar system cost?
Complete systems on this page range from roughly $9,700 to $39,600, depending on inverter size and how much storage you choose. That covers the equipment; installation, permits and racking are additional and vary by site.
Do I need an electrician?
Yes. These systems connect to your main service and involve high DC voltages. Design, installation and inspection must be carried out by a licensed electrician or professional engineer, to the National Electrical Code and any local amendments.
Will it work with my existing solar panels?
Often, if the array voltage and current fit within the hybrid inverter's limits. Send us your panel model and how they are wired, and we will check it before you order.
