PROTECTIONS
| PROTECTION | DESCRIPTION |
|---|---|
| Input under/over-voltage | When the AC input voltage is lower than 150Vac, the charger stops working and an under-voltage alarm occurs; when the AC input voltage is higher than 280Vac, the charger stops working and an over-voltage alarm occurs; |
| Input overcurrent | The charger reduces the output power to ensure that the input over current (active monitoring) thresholds are not breached. |
| Output over-voltage | If output voltage exceeds the internal OV threshold, the charger immediately cuts the output relay and gives an alarm. |
| Output overcurrent | If load current exceeds the internal OC limit, the charger immediately cuts the output relay and gives an alarm. |
| Output short circuit | If the output is short-circuited, the charger shuts down output with current limit and an alarm is issued. |
| Reverse polarity & no-load | If the battery is connected in reverse, the charger shuts down output and alarms (reverse polarity protection not active during Activation mode). If battery voltage is missing or <⅓ of rated pack voltage, the charger alarms and gives no output. |
| Automatic shutdown | If charging time or charging end voltage exceeds the internal maximum limit, it stops charging and alarms. |
| Over-temperature | If internal or ambient temperature goes above the set value, it first reduces current (derating), then stops and alarms; charging resumes automatically when temperature falls to the recovery point. With an external probe, it can also monitor battery/ambient temperature. |

Additional Details
The STTL3000BG8435L is a 2950 W certified portable charger for 84 V lithium packs, part of Solterra’s BG certified series for North America and Europe. It accepts a wide single-phase three-wire input (120 V and 230–240 Vac; 85–270 Vac range) with an adaptive-grid strategy — 2950 W at 230 Vac, 1200 W at 120 Vac on a 5-15P plug and 1500 W at 120 Vac on a 5-20P plug or distribution — and delivers a constant-power output of 66–103 Vdc at up to 35 A with 90% efficiency, PF 0.99 and a pure sine waveform.
It is internationally certified — UL, CB, CE, FCC, KC, KCC, RCM, CEC, DOE, CP65 and ECE R10 — IP65-sealed, forced-air cooled, and protected against input/output over- and under-voltage, overcurrent, short-circuit, reverse polarity, over-temperature (with derating) and over-time charging. A 12 V/3 A or 12 V/5 A auxiliary output, optional CAN and a CANbus programming interface support integration; the unit mounts both as a portable charger and onboard.
