Cycle ratings use different test conditions and are not directly comparable service-life forecasts. Warranty years reflect the cited listing, subject to the written terms for your country, seller and exact model. Rs. / kWh uses nominal capacity and excludes installation, conversion losses and future replacements.
Every battery, every detail
Capacity, chemistry, cycles, voltage, protocol, inverter compatibility, dimensions, and best use case.
LFP, NMC, or Lead Acid?
Compare complete products and installation conditions. Cycle life and capacity retention cannot be assigned to a chemistry with one universal figure.
A common option for stationary home storage. Compare the exact model's safety documentation, cycle test conditions, temperature limits, BMS support and inverter compatibility. Chemistry alone does not determine service life.
NMC products vary in design and thermal management. Check the complete system's certification, installation requirements, manufacturer support and warranty; a used EV pack needs specialist assessment before stationary reuse.
Lead-acid can suit occasional backup, but usable depth of discharge and cycling duty depend on the model. Compare replacement costs, charge settings, ventilation needs and the manufacturer's discharge curves before choosing it for daily solar use.
How much battery does your home need?
Battery sizing is about backup hours, not just kWh. Three common Pakistani scenarios — pick the one that matches your loadshedding needs.
8 things to check before you buy
Compare the complete battery
LFP is a common home-storage choice, but chemistry alone does not establish safety or value. Check product certification, BMS support, installation limits and after-sales service for the exact model.
Match usable capacity to load
Nominal kWh × allowed DoD estimates usable DC energy before conversion losses. For example, 5.12 kWh × 95% is about 4.86 kWh. Reserve settings, load, battery condition and inverter losses reduce energy reaching appliances. Confirm the required discharge power as well as kWh.
Read the applicable warranty
A five-, eight- or ten-year listing is not proof of a battery's lifespan or quality. Coverage depends on country, seller, exact model, registration, installation and operating conditions. Check capacity-retention and throughput limits, exclusions, claim handling and any separate product/service periods in writing.
Treat throughput as an illustration
6,000 cycles × 5.12 kWh × 95% DoD = 29,184 kWh is illustrative arithmetic assuming unchanged capacity each cycle. It ignores degradation, calendar aging, efficiency and downtime; it is not promised lifetime energy. Compare cycle ratings only with their test conditions and end-of-test capacity criteria.
Use the supported communication mode
CAN and RS485 can both support battery/inverter communication. Neither interface name guarantees better charging or longer life. Follow the manufacturer's compatibility list, port, cable pinout, protocol profile, DIP settings and firmware requirements for the exact pair.
Inverter compatibility
Not every battery works with every inverter firmware. CAN or RS485 on both labels is not enough: verify the exact model pair, communication cable and supported firmware before purchase.
Indoor vs outdoor mounting
Most listed batteries are IP20 or IP21 and belong indoors. Pylontech FIDUS is listed as IP65, but even a weather-resistant enclosure should be shaded, ventilated and installed within its temperature limits.
Modular = future upgrade
Modular Pylontech, Dyness and BYD systems can add capacity later. Standalone and wall-mounted batteries may also support parallel units, but match brand, model, age and BMS settings to avoid imbalance.
