- Capacity: 4,800 Wh total, 4,560 Wh usable at 95% depth of discharge
- System voltage: 48 VDC, charge 52.5–53.5 V, discharge 43.5–53.5 V
- Current: 100 A continuous charge/discharge (80 A recommended), peaks to 200 A for 15 seconds
- Cycle life: over 8,000 cycles at 25°C, 15+ year design life
- Key limitation: IP20 — indoor installation only, never outdoors or anywhere exposed to driven rain
The Pylontech US5000 is a 4.8 kWh, 48 V LiFePO4 battery module in 19-inch rack format — one of the most widely deployed storage products in residential and small commercial solar. Its strength is scalability: start with a single 4.8 kWh unit and expand to 16 units per group for 76.8 kWh, with broad compatibility across the hybrid inverters we install from Deye, Solis, Growatt and Victron. The critical constraint is its IP20 rating, which restricts it to indoor installation.
What is the US5000, and why is it so widely used?
The US5000 is a low-voltage 48 V battery module designed for standard 19-inch racks or the manufacturer's stacking shelves. Each unit has an integrated BMS and communicates with the inverter over CAN or RS485 to report state of charge and temperature, and to limit current when required. Three things explain its popularity. First, compatibility: the manufacturer's list covers Deye/Sunsynk SG01LP1, SG03LP1, SG04LP1 and SG04LP3 families, several Solis S5 and S6 models, Growatt SPF and M series, and Victron MultiPlus/Quattro through Venus OS. Second, genuine expandability: start with one unit and add up to 16 later without changing the inverter. Third, cycle life above 8,000 cycles — at one full cycle per day that is over twenty years in theory, though in practice temperature and usage pattern limit service life more than cycle count does.
Highlights from the datasheet
- Expandable to 16 units: up to 76.8 kWh per group, starting from a single module and growing with budget and demand
- 95% DoD, 4.56 kWh usable: far more of the nameplate capacity is available than with lead-acid, where roughly half is practical
- 8,000+ cycles at 25°C: at the upper end for residential LiFePO4 storage
- Broad inverter compatibility: Deye/Sunsynk, Solis, Growatt and Victron per the manufacturer's list — always verify exact model and firmware before ordering
- 100 A continuous current: handles household peak loads, with 200 A available for 15 seconds for motor starting
- 19-inch rack format: tidy installation and easy inspection when several units are stacked
- 7-year warranty, 10 years free on registration: guaranteeing 70% remaining capacity at 7 years, or 60% at 10

Why this model suits Phuket
- 🔴 IP20 means indoors only: in a wet, humid climate this battery must sit in an enclosed room with no driven rain and no flood risk — we fix the location during the site survey
- Room temperature drives battery life: a hot, unventilated store room shortens service life; we specify a ventilated or cooled space
- Storm-season outages: 4.8 kWh per unit covers a home's essential circuits overnight, with more units added as needed
- Practical size: 442 × 420 × 161 mm and 39.7 kg per unit, mounting into a rack or shelf in the plant room
Who it suits
- Homes that want to start small and expand: one 4.8 kWh unit now, more later
- 48 V low-voltage hybrid systems: paired with Deye, Solis, Growatt or Victron inverters from the approved list
- Properties with an indoor plant room: store room, laundry or enclosed garage
- Small businesses: shops, clinics or offices backing up a few kilowatts of essential load
- Projects that value documented compatibility: Pylontech publishes a detailed inverter compatibility list
Summary
The Pylontech US5000 suits Phuket homes and small businesses that want to start with modest storage and expand later: 4.56 kWh usable at 95% DoD, over 8,000 cycles, and compatibility with the hybrid inverters we install. The constraint to design around is the IP20 rating, which mandates indoor installation. Where outdoor mounting is unavoidable, the IP65-rated Pelio-L is the better choice.
