Every battery, every detail
Capacity, chemistry, cycles, voltage, protocol, inverter compatibility, dimensions, and best use case.
LFP, NMC, or Lead Acid?
For Pakistani homes, LFP is usually the safest default, but compatibility and heat management still decide real life.
The practical default for stationary home storage: safer chemistry, high cycle life, and good fit for hybrid solar backup. Still verify BMS quality, installation temperature, and inverter compatibility.
Higher energy density (smaller for same kWh) but shorter cycle life and higher thermal risk. Phased out for residential storage since 2023. Only relevant if you're considering used EV battery packs.
Legacy tech. Cheapest upfront but life-cycle cost is 3-4× higher than LFP because they wear out in 3-5 years. Heavy, can't be deep-discharged below 50%. Avoid for any new install.
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
LFP chemistry only
For most new hybrid systems, LFP beats lead-acid and older lithium chemistries on safety, usable depth, and cycle life. Only consider AGM/gel for very small budgets or temporary backup.
Match usable capacity to load
Don't compare nominal capacity (kWh on box). Compare usable capacity = capacity × DoD. A 5.12 kWh battery at 95% DoD gives about 4.86 kWh usable, while a 5.12 kWh battery at 90% DoD gives about 4.6 kWh usable. Then compare cycle life and warranty.
10-year warranty minimum
LFP batteries last 10-15 years. Anything with less than 10-year warranty is selling on price, not quality. Read the warranty fine print — capacity retention claim matters more than coverage years.
Cycles × DoD × kWh
Real lifetime energy = cycles × usable capacity. A 6000-cycle 5.12 kWh battery at 95% DoD delivers about 29,000 kWh over its life. An 8000-cycle battery at similar usable capacity can justify a higher upfront price. Compare Rs. per lifetime-kWh, not Rs. per nominal kWh.
CAN protocol > RS485
CAN bus lets battery and inverter share detailed state-of-charge data — slower charge tapering, better lifespan. RS485 works but is older. If your inverter supports CAN, pick a CAN battery.
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.
