⚠️ Safety Precautions

• !
  Qualified Installation Only — installation, wiring, and servicing must only be performed by trained, qualified personnel.
• !
  No Reverse Polarity — always connect Positive (+) to Positive (+) and Negative (−) to Negative (−). Never reverse polarity.
• !
  Switch Off Before Wiring — always switch the battery OFF before connecting or disconnecting any cables, and never short-circuit the terminals.
• !
  Ventilated, Dry Location — install in a well-ventilated, dry location out of reach of children; never open the enclosure, which has no user-serviceable parts inside.
• !
  Series Connection Restricted — only battery models explicitly approved by Electronium for series operation should ever be connected in series; combining non-approved models in series may cause permanent damage and voids the warranty. See Series Connection below.

🔌 Wiring Guide

Safe Connection Procedure (Single Battery to Inverter)

• 1
  Wear insulated safety gloves. Wrap the positive and negative cable ends with insulating tape to prevent accidental short circuits.
• 2
  Unscrew the positive terminal cover, connect the positive wire, and refit the protective cover.
• 3
  Unscrew the negative terminal cover, connect the negative wire, and refit the protective cover.
• 4
  At the inverter end, connect the positive wire, then the negative wire, and refit the inverter's terminal covers.
• 5
  Turn ON the battery's main air switch.
• 6
  Press and activate the battery's power switch.
• 7
  Wait at least one minute, then power on the inverter.

🔗 Inverter Connection

Electronium batteries communicate with a wide range of inverter brands over CAN and/or RS485. Always verify compatibility with your specific inverter model/firmware and select the matching protocol in the battery's communication settings before first use.

Commonly Used Inverters

• ✓
  Deye — CAN / RS485
• ✓
  Growatt — RS485 / CAN
• ✓
  Sofar Solar — CAN
• ✓
  Voltronic — RS485
• ✓
  Victron Energy — CAN
• ✓
  Pylontech, GoodWe, Solax Power, Sungrow, SMA, and 25+ other brands — see the full compatibility table on our Manual Details page.

If your inverter brand isn't listed, contact Electronium technical support with your inverter's make and model — a matching communication protocol can often be supplied.

📱 Battery Monitoring & the Electronium Link App

Electronium batteries can be monitored through several channels simultaneously:

• 📶
  Electronium Link app via Bluetooth — local monitoring, available on all models
• 📡
  Electronium Link app via WiFi — remote monitoring with the optional WiFi module
• 🖥️
  On-unit LCD touch screen — selected models, shows real-time status even without networked monitoring
• 🔗
  Inverter display — via CAN or RS485 communication

What You Can Monitor

• 📊
  Individual cell voltages, overall pack voltage, and charge/discharge current
• 🌡️
  Cell, MOS, and environment temperature readings across multiple sensor points
• 🔋
  SOC (State of Charge), remaining capacity, and full-capacity calibration
• ⚙️
  Active alarms, protections, and faults — plus firmware version and hardware info on the LCD Setup page

💡 LED Indicator Guide

Models without an LCD screen provide status feedback via 6 LEDs: four green SOC/capacity indicators (SOC1–SOC4), one red alarm indicator (ALM), and one green running indicator (RUN).

• 🟢
  Charging — Normal: LEDs fill upward, top LED blinks, RUN is solid on, ALM is off.
• 🟢
  Discharging — Normal: LEDs show SOC level, RUN blinks fast, ALM is off.
• 🟡
  Alarm Active: ALM blinks fast alongside the normal charging/discharging pattern — check the app for the specific fault.
• 🔴
  Failure / Protection Engaged: SOC LEDs all off, ALM solid on, RUN off — disconnect and check the alarm log before reconnecting.

🔄 Parallel Battery Setup (Multi-Pack)

Up to 16 Electronium batteries of the same model can be connected in parallel through the dedicated battery parallel communication bus (not the inverter CAN/RS485 port) to build larger energy banks.

• 1
  Assign each battery a unique address using its internal DIP switches (#1–#4 in binary). Address 0 is always the host (Pack 0); all others are slaves.
• 2
  Link batteries pack-to-pack via the dedicated RS485 parallel port, forming a daisy chain from the host through each slave pack.
• 3
  The host pack communicates with the inverter over CAN or RS485, summarizing data from every slave pack in the chain.
• 4
  DIP switches #5–#6 (host unit only) select the inverter communication protocol family; on slave packs, #5–#6 must remain OFF.
• 5
  Keep the length of each power cable to the busbar consistent, so current is shared evenly across all units.

➕ Series Connection

• ✓
  Use identical battery models and firmware versions only.
• ✓
  Ensure all batteries are at equal SOC before connecting in series.
• ✓
  Contact Electronium technical support before attempting a series configuration.

🛠️ Maintenance, Storage & Transportation

Monthly Inspection Checklist

• ✓
  Check that all terminal connections remain tight and corrosion-free.
• ✓
  Inspect wiring for wear, chafing, or heat damage, and clean dust from ventilation openings.
• ✓
  Verify pack voltage and cell balance via the Electronium Link app or LCD display, and check for any historical alarms.
• ✓
  No water topping or electrolyte maintenance is ever required — Electronium LiFePO₄ batteries are maintenance-free by design.

Storage

• ✓
  Store at 20%–60% State of Charge (SOC) for any period of non-use, in a dry location away from direct sunlight (25°C ± 3°C recommended).
• ✓
  Recharge at least once every 3 months, and perform one complete charge/discharge cycle every 6 months during long-term storage.

Transportation

• ✓
  Transport in the original packaging whenever possible; avoid impact, vibration, rain, and moisture.
• ✓
  Confirm the battery is fully disconnected before transport, with no charge/discharge current flowing.
• ✓
  If a unit is dropped, exposed to water, or otherwise damaged in transit, isolate it and have it inspected by a qualified professional before use.
