Short answer: For a compatible 48V solar or hybrid inverter, our recommended Nexus options are the 51.2V 100Ah LCD battery at ₹1,08,748.80 and the 51.2V 100Ah Pro at ₹1,35,700.00, including GST. Both have 5.12kWh nominal capacity. Choose by the exact inverter voltage window, BMS current and communication requirements, rather than the 48V label alone.

LCD and Pro: select the exact variant
We do not treat the Pro as universally better for every load. Confirm what its quoted warranty, BMS current and communication support provide for your actual inverter. Compare the full system proposal before paying for a higher-priced variant.
Lithium battery for hybrid inverter: the compatibility checklist
- Battery nominal voltage and full operating voltage window.
- Maximum permitted inverter battery charge current, including combined solar and grid charging.
- Battery continuous discharge current, peak current and permitted peak duration.
- BMS protocol, inverter support list, connector pinout and firmware version if closed-loop communication is used.
- Approved lithium voltage settings and fault behaviour if an open-loop mode is supported.
- Cable cross-section, cable length, fuse/breaker, isolation, polarity, earthing and mounting specified for the installation.
- Exact pack expansion permission, parallel limit and commissioning sequence.
Supported configurations include Nexus and DEVSOL inverters and supported Deye / Voltronic protocol configurations. Match exact battery voltage, inverter model, BMS protocol, cable pinout and firmware; this is not universal compatibility with every model.
100 Ah lithium battery: kWh is energy, kW is load power
Nominal energy equals nominal volts multiplied by amp-hours, divided by 1000. 100 Ah at 12.8 V is 1.28 kWh; 100 Ah at 25.6 V is 2.56 kWh; 100 Ah at 51.2 V is 5.12 kWh. These packs all say 100 Ah but store different amounts of energy. A 5.12 kWh pack is not automatically a 5.12 kW output device.
Illustrative runtime equals nominal kWh × permitted usable fraction × inverter efficiency ÷ average AC load kW. With assumed 80% usable capacity and 90% efficiency, a 5.12 kWh pack gives about 3.69 kWh AC; a 2.56 kWh pack gives about 1.84 kWh AC. Divide that energy by your measured average load. These are sizing examples, not tested runtime claims for a Nexus model.
Power needs a separate current check. At an assumed 90% efficiency, 5 kW AC requires about 217 A DC at 25.6 V or 109 A DC at 51.2 V. Current rises as voltage falls. The manufacturer confirms a 100A continuous ceiling and 50A recommended discharge for these 100Ah packs. Both example 5kW currents exceed that single-pack ceiling; use an approved appropriately sized battery arrangement instead. Do not size an AC, pump or refrigerator from nominal running watts alone: starting loads and the inverter surge limits matter.
Manufacturer-confirmed battery and smart BMS specifications
Nexus Premium packs are rated at 4,500+ cycles, Nexus Eco at 3,000+ cycles and DEVSOL Premium / Pro at 6,500+ cycles. These are manufacturer-declared cycle-life ratings, not independent laboratory results; no unstated depth of discharge, temperature or retained-capacity test condition is implied.
| Pack configuration | Nominal energy at 100Ah | Continuous discharge limit | Recommended discharge at 0.5C | Display and expansion |
|---|---|---|---|---|
| 4S / 12.8V 100Ah | 1.28kWh | 100A | 50A | No LCD; no parallel feature |
| 8S / 25.6V 100Ah LCD | 2.56kWh | 100A | 50A | LCD and approved same-model parallel expansion |
| 16S / 51.2V 100Ah LCD / Pro | 5.12kWh | 100A | 50A | LCD and approved same-model parallel expansion |
For a 200Ah configuration with a 200A BMS, the continuous discharge limit is 200A and the recommended 0.5C discharge is 100A. This configuration statement does not establish that a 200Ah retail model is currently available. Ah describes stored charge; A describes current. The BMS ceiling is not the recommended everyday load.
LCD-equipped models provide a cycle counter, individual cell-voltage readings and temperature readings. Smart BMS protection includes temperature monitoring and cell balancing. Active or passive balancing depends on the installed variant; Pro features must be checked against its exact product specification. Eco and 4S models have no LCD or parallel feature. Use an approved matched-pack expansion arrangement, wiring, current protection and commissioning procedure.
Supported inverter configurations include Nexus and DEVSOL, and supported Deye and Voltronic protocol configurations. Match the exact inverter model, voltage range, protocol, cable pinout and firmware. A protocol family or CAN/RS485 connector alone is not universal compatibility.
At nominal voltage and an illustrative 90% inverter efficiency, recommended 50A discharge corresponds to about 0.58kW AC at 12.8V, 1.15kW at 25.6V and 2.30kW at 51.2V. At the 100A ceiling these illustrative values double. Actual permissible load falls with battery voltage and depends on inverter limits. A single 51.2V 100Ah pack must not be promised to provide continuous 5kW AC: even at nominal voltage this requires approximately 109A at 90% efficiency.
BIS coverage is limited to the certified 12V battery model. It does not extend to the 25.6V or 51.2V packs. Match the exact 12V nameplate to the certificate model annex before purchasing on a certification requirement. The available renewal is not a cycle-life test report.
For products offered with 15-year* warranty terms, the published policy provides three years of free replacement for covered manufacturing faults, followed by replacement at a 50% MRP discount in years 4–15, subject to its conditions. This is not 15 years of free replacement and does not replace the separate terms of a 5-year model. See the current warranty terms and your exact model’s invoice / warranty card.
Frequently asked questions
Which Nexus lithium battery is best for a 48V solar inverter?
Our candidates for a compatible 48V-class solar or hybrid inverter are the Nexus 51.2V 100Ah LCD and Pro LiFePO4 packs. Both store 5.12kWh nominally. Compare the exact BMS current rating, charging settings, communication support and written warranty before choosing.
Is a 5.12kWh battery the same as a 5kW battery?
No. 5.12kWh is nominal stored energy. Maximum output power depends on battery current limits and operating voltage, as well as the inverter. Do not infer a 5kW continuous rating from energy capacity.
Can a 51.2V 100Ah battery run a 5kW hybrid inverter?
A single 51.2V 100Ah pack has a manufacturer-confirmed 100A continuous discharge limit, with 50A recommended at 0.5C. At illustrative 90% inverter efficiency, 5kW AC requires about 109A at nominal voltage and more as voltage falls, exceeding that single-pack limit. Use an approved larger or matched parallel arrangement and correct inverter settings.
Can 12.8V packs be connected in series to make 51.2V?
Only when the exact battery manufacturer explicitly allows that series configuration and its BMS supports it. Parallel-expansion permission is not permission for series wiring.
