Pylontech vs Dyness: Which Battery Should You Choose?

Both Pylontech and Dyness make LiFePO4 (lithium iron phosphate) batteries widely used in Pakistan for hybrid solar systems, and both are compatible with most major hybrid inverters. The real differences come down to module size, stacking flexibility, and how the batteries fit into the physical space you have available. Here's how they compare on the numbers.

Pylontech (US2000C / US3000C / US5000)

ModelUsable CapacityDimensions (W×D×H)WeightMax Charge/Discharge Current
US2000C2.28 kWh442×410×89 mm22.5 kg25 A
US3000C3.37 kWh442×420×132 mm32 kg37 A
US50004.56 kWh442×420×161 mm~40 kgup to 80 A

All three Pylontech models run on a 48V nominal system, communicate over CAN/RS485, carry a 15+ year design life, and are rated for over 6,000 cycles at 25°C. They stack in a standard 19" rack format, which is why you'll see them installed in rack cabinets rather than mounted flat against a wall.

Dyness (BX51100)

SpecBX51100
Nominal Capacity5.12 kWh (100 Ah)
Nominal Voltage51.2V (operating range 44.8–57.6V)
Dimensions (W×D×H)558×545×150 mm
Weight~50 kg
Max Charge/Discharge Current75–100A (110A peak)
Cycle Life / Warranty6,000 cycles / 10-year warranty
Scalability5.12 kWh to 153 kWh (up to 30 units in parallel)

Dyness supports wall-mounted, floor-standing, or stacked installation, and communicates over CAN/RS485/RS232. It's compatible with a wide range of inverter brands including Goodwe, SMA, Victron, Growatt, Deye, and Voltronic.

Which one fits your situation?

Both brands are solid, datasheet-verified options — the right choice depends on your available space, your backup hours needed, and whether you plan to expand later. We size and quote both options side-by-side as part of every proposal, based on a free site survey.
