Remote on/off of Battery

Traditionally, Batteries were controller purely by an electrical isolator. With the advent of a smarter BMS, remote on/off of the battery packs is possible with a remote switch. However, if an inverter or any device that uses capacitors is being activated by the battery then care should be taken to let the battery fully turn on first BEFORE engaging the inverter or pre-charging capacitors. The battery pack has a maximum discharge overcurrent protection of 170 A for 10 s, an instantaneous overcurrent protection of 250 A for 30 ms, and a short-circuit protection threshold of 350 A for 100 μs. The battery pack has been proven to pre-charge at 1A absolute maximum current a 30,000uf capacitor providing this can be done within 2 seconds. If the current is more than exactly 1A or the time more than 2 Seconds the battery BMS will fault.

The battery pack will not trigger pre-charging in standby mode.

Pre-charging is only activated at power-on or after recovery from short-circuit protection.

Connection of multiple batteries for a larger capacity DOES NOT SOLVE THIS PROBLEM Why Multiple Parallel Packs Dont Solve the Problem Even though you have multiple packs, the inrush is assessed battery by battery for safety reasons. They communicate and "handshake" over the 485 bus and if a pack does not pass the inverter inrush: If Pack 1 tries to engage and trips its protection because of the inverter's size, it drops off the bus. Then Pack 2 tries, trips, and drops off. This creates a "popcorn effect" where the slave batteries drop out one by one because none of them individually can handle the massive "thirst" of the inverter's capacitors during that first millisecond.

UNIVERSAL BEST PRACTICE IS:

ISOLATE THE BATTERIES WITH A PHYSICAL ELECTRICAL ISOLATOR TURN ON THE BATTERIES AND WAIT 5 SECONDS ACTIVATE THE INVERTER PRE-CHARGE CIRCUIT. Wait for the required pre-charge time.

TURN ON THE INVERTER.

Installation Guidelines

Ensure correct polarity when connecting batteries

Batteries can be stacked and connected in parallel

Don not connect in Series, parallel operation only

Connect batteries sequentially from "Out" of the master to "In" of the subsequent units

Press "Reset/On" button on the Master battery to initiate operation

Interconnecting Power Straps

These are made from high grade copper, tin coated flexible fused straps. Their dimensions are 25mm wide and 2mm thick with a cross section of 50mm2

The MAX safe current rating of these straps is 250A

CAN Bus Battery Management System (BMS) Protocol

1. General CAN Specifications

CAN Frame Format: Standard 11-bit identifier (CAN 2.0A) Bitrate: 250 kbps Termination: At least one CAN bus termination is required; built-in termination in the solid state battery Isolation: Battery CAN ports are isolated; minimum required wiring is GND, CAN-H, and CAN-L

2. CAN IDs: Messages from BMS to Inverter/Controller

Alarm/Warning Encoding for 0x35A

Bit pairs:

00 - Not supported 10 - Active 01 - OK

11 - Reserved

Note on CVL/CCL/DCL Strategy

Do not send CCL = 0 to stop charging. Instead, reduce CVL . DCL = 0 disables discharge entirely. Use dynamic CVL adjustment to avoid overvoltage or unintentional discharging.

CAN Bus Battery Management System (BMS) Protocol

3. Messages from Inverter/Controller to BMS

CAN ID 0x305 0x307

DESCRIPTION Keepalive Inverter Identification

FORMAT 8 bytes: all 0x00 Bytes 4–6: ASCII 'VIC' (legacy)

Timeouts: 4. Timing & Communication Guidelines

BMS should tolerate loss of 0x305 for 10 minutes . Inverter stops operation if 0x351 is not received within 3 seconds .

5. Implementation Advice

Use 11-bit identifiers only. Avoid 29-bit IDs even though mixed-mode is technically possible. All current values should be positive regardless of direction. SOC high-res field is optional. Use ASCII encoding (7-bit) for all name and string fields.

6. Testing Checklist

Ensure CAN communication is visible (e.g., via candump) Confirm correct reception of 0x351, 0x355, 0x356, 0x35A Validate alarm flag encoding Validate proper reaction to CVL/CCL changes in DC-coupled solar systems Confirm safe shutdown and recovery from blackout events Check full set of extended fields if implemented (0x372–0x382)
