Installation
| busbar_requirement | EG4 recommends a properly amp-rated busbar to parallel batteries |
| cable_requirements | supplied 4 AWG positive and negative connection cables; above 30 C (86 F) ambient the cable size must be increased per NEC 310 |
| commissioning_note | each battery must be charged individually to 100% before paralleling |
| grounding_requirements | ground the rack/cabinet to an equipment grounding conductor; do NOT ground the rack/cabinet or door to the negative or positive busbars |
| indoor_outdoor | indoor (IP20) |
| mounting_orientation | horizontal rack module |
Environment
| charge_temperature_c |
0 to +45 (v2); 0 to +50 (v3)

| cooling_method | natural convection |
| discharge_temperature_c | -20 to +50 (v2); -20 to +55 (v3) |
| ip_rating | IP20 |
| max_altitude_m | UNKNOWN |
| relative_humidity | UNKNOWN |
| storage_temperature_c | UNKNOWN |
Interfaces & connectors
| can | yes - RJ45 pin3 CAN ground (optional), pin4 CAN High, pin5 CAN Low |
| protocol_notes | Cat5e or better required. Battery ID range 1-64 on a 6-position DIP switch; every battery must have a unique ID. v2 units with no DIP switch use Auto-ID, which performs both protocol detection and ID assignment. |
| rs485 | yes - RJ45 pin1 RS485-B, pin2 RS485-A; battery-to-battery uses pin7 RS485-B / pin8 RS485-A |
Protection
| cell_balancing | UNKNOWN |
| integrated_breakers_fuses | front-panel DC circuit breaker; ampere rating not printed in the quick-start guide |
| over_current | yes (>150 A trips over-discharge protection in 3 s) |
| over_temperature | yes |
| over_voltage | yes |
| short_circuit | yes |
| under_voltage | yes |
