Product Overview
The JK-PB1A16S-20P is a 200A smart inverter BMS designed for 16S lithium battery packs in residential and commercial energy storage. It pairs a 1A active balancing circuit with RS485, CAN, and RS232 inverter communication, so the pack reports cell data directly to mainstream hybrid inverters while staying balanced in real time.
Built on the V14.0 platform, it delivers 200A continuous discharge, 25A charge current, and 550A short-circuit protection with a 30µs cutoff. Installers get a 3.2-inch color LCD, Bluetooth mobile app, and PC host software for full local and remote visibility — plus parallel expansion for up to 16 packs via DIP-switch addressing.
For closed-loop setup steps, follow our inverter RS485/CAN communication guide.
Core Features
- 1A Active Balancing: Selectable 0.4A / 0.6A / 1A / 2A balancing with LED indicators transfers energy between cells instead of burning it off, extending pack life and usable capacity.
- 200A High-Current Output: 200A continuous discharge with 550A short-circuit protection (30µs), plus overcharge, over-discharge, and over-current safeguards.
- Inverter Communication: RS485 (×2, one for parallel), CAN bus, and RS232 interfaces talk directly to mainstream hybrid inverter protocols.
- Full Visibility: 3.2-inch color LCD, Bluetooth app, and PC software show cell voltages, temperatures, and SOC locally or remotely.
- Parallel Expansion: Link up to 16 packs in parallel over RS485 with 4-bit DIP-switch addressing (0–15).
- Climate & Integration Ready: 4-channel temperature detection with MOS protection, configurable low-temperature heating, dry-contact alarm outputs, buzzer, and a 1000-entry event log.
Application Scenarios
Made for daily-cycling storage, the JK-PB1A16S-20P suits residential energy storage systems, commercial and industrial battery cabinets, 16S LiFePO4 solar packs, off-grid and hybrid inverter installations, and telecom base station backup.
Frequently Asked Questions
Which inverters can the JK-PB1A16S-20P communicate with?
The JK-PB1A16S-20P communicates with mainstream hybrid inverters over RS485 and CAN protocols, so your energy storage system and inverter stay in sync on charge/discharge control. Share your inverter brand and model with our engineers and we will confirm protocol compatibility before you order.
Can I connect several JK-PB1A16S-20P units in parallel?
Yes. The JK-PB1A16S-20P supports parallel connection of battery packs with DIP-switch addressing, which makes it easy to scale up to larger commercial and industrial energy storage systems. A 3.2-inch LCD on the unit shows real-time status without needing the app.
What kind of battery is the JK-PB1A16S-20P designed for?
The JK-PB1A16S-20P is built for 16S LiFePO4 energy storage systems with 200A continuous discharge current, full protection (over-charge, over-discharge, over-current, short circuit, over-temperature) and active cell balancing.
