Hybrid Inverter

How to Choose the Right Hybrid Solar Inverter for Your Home or Business
A hybrid solar inverter is the brain of your solar power system. It takes power from solar panels, charges your battery, runs your home appliances, and connects to the grid — all at the same time. If you are buying a solar system for the first time, or upgrading from a basic inverter, this guide helps you pick the right hybrid inverter for your needs.

How to Choose a Hybrid Solar Inverter (kW Selection by Home Size)
The first thing to decide is how much power you need. This depends on the size of your home or shop and the appliances you run.
2–3 BHK Home (1–2 ACs, fridge, fans, lights)
A 3kW to 5kW hybrid inverter works well for most 2-3 BHK homes. This covers your daily electricity needs during the day from solar panels and provides battery backup at night.
4 BHK Home or Small Office (2–3 ACs, printer, multiple fans)
Go for a 6kW to 8kW hybrid inverter. Larger homes with more appliances need higher capacity to run everything smoothly without overloading the system.
Shop, Clinic, or Small Factory (heavy equipment, multiple machines)
A 10kW to 15kW hybrid inverter is the right fit. These higher-capacity models handle commercial loads and provide enough backup for extended power cuts.
Simple Rule: Add up the wattage of all appliances you want to run at the same time. Divide by 1,000 to get the kW size you need. Always keep a 20% margin for future additions.

24V vs 48V: Which One Do You Need
The battery voltage of a hybrid inverter matters for system efficiency and cost.
24V Systems
Best for smaller setups — 2kW to 5kW inverters. A 24V system uses fewer batteries and works well for homes with moderate power needs. If you have a small home or shop and want a simple, affordable setup, 24V is a good choice.
48V Systems
Used in 6kW to 15kW inverters. A 48V system is more efficient for higher power loads because it draws less current from the battery, which means thinner cables and less energy loss. For larger homes, offices, and commercial setups, 48V is the standard.
When to choose 48V over 24V:

Your inverter capacity is 6kW or above
You plan to run multiple ACs or heavy appliances
You want better long-term efficiency

Lithium vs Lead-Acid Battery Compatibility
Most hybrid inverters today support both lithium and lead-acid batteries. But the two battery types work very differently.
Lead-Acid Batteries

Lower upfront cost
Heavy and need regular water topping
Typical life: 3–5 years
Work fine for basic backup needs

Lithium Batteries (LiFePO4)

Higher upfront cost, lower cost over 10 years
Lightweight, zero maintenance
Typical life: 8–10 years with 3000+ charge cycles
Charge faster and discharge deeper without damage

Which one should you choose?
If budget is tight now, lead-acid batteries work. But if you plan to use the solar system for 8–10 years, lithium batteries save money in the long run because you avoid 2–3 battery replacements.
All Nexus hybrid inverters support both lithium and lead-acid batteries. Check the specific model for compatibility details before purchasing.

Features That Set the Nexus Hybrid Range Apart
Battery-less operation. Every Nexus hybrid inverter can run without a battery connected, working like an on-grid system. Install panels and the inverter now, save on your bill from day one, and add a battery later when you want backup.
Parallel and three-phase capability. The 6kW, 8kW, 10kW and 11kW parallel-capable models can be combined for larger systems and configured as single-phase or three-phase — suitable for workshops, institutions and small factories.
Generator synchronization. The inverters can sync with a diesel generator, letting solar, grid, generator and battery work together in one system.
High-current MPPT options. Charge controller variants up to 100A and 160A support larger battery banks with faster charging.
Four battery chemistries. Lead-acid, tubular, lithium and sodium batteries are all supported — you are never locked into one battery type.
Remote operation, touch screen, full protection. Monitor and operate the system remotely, control it via touch screen, and rely on built-in electrical protection.
Made and repairable in India. The full range is designed and manufactured in India under the direction of founder Deepak Chaudhary, with repair support within India — no imported-spare-part delays.
