6. Solució De Problemes
This section outlines common issues and their potential solutions. For more complex problems, contact technical support.
| Problema | Causa / Solució |
|---|---|
| PV Overcurrent/Power | Ensure the open-circuit voltage of the PV array does not exceed the maximum PV open-circuit voltage. Otherwise the controller may be damaged. |
| Circuit curt de PV | Quan no estigui en estat de càrrega fotovoltaica, el controlador no es farà malbé en cas d'un curtcircuit a la matriu fotovoltaica. |
| PV inversa polaritat | When the polarity of the PV array is reversed, the controller may not be damaged and can continue to operate normally after the polarity is corrected. NOTE: If the PV array is reverse connected to the controller, 1.5 times rated controller power (watts) from the PV array, will damage the controller. |
| Càrrega inversa nocturna | Evita que la bateria es descarregui a través del mòdul fotovoltaic durant la nit. |
| Polaritat inversa de la bateria | Fully protected against battery reverse polarity; no damage to the controller will result. Correct the miswire to resume normal operation. |
| Battery Over Voltage | Quan la bateria voltage arriba al sobre voltagi desconnectar voltage, aturarà automàticament la càrrega de la bateria per evitar danys a la bateria causats per una sobrecàrrega. |
| Descàrrega excessiva de la bateria | Quan la bateria voltage arriba al baix voltagi desconnectar voltage, aturarà automàticament la descàrrega de la bateria per evitar danys a la bateria causats per una sobredescàrrega. (Qualsevol càrrega connectada al controlador es desconnectarà. Les càrregues connectades directament a la bateria no es veuran afectades i poden continuar descarregant la bateria.) |
| Sobreescalfament de la bateria | El controlador pot detectar la temperatura de la bateria mitjançant un sensor de temperatura extern. El controlador deixa de funcionar quan la seva temperatura supera els 65 °C i comença a funcionar quan la seva temperatura és inferior a 55 °C. |
| Lithium Battery Low Temperature Protection | When the temperature detected by the optional temperature sensor is lower than the Low Temperature Protection Threshold (LTPT), the controller will stop charging and discharging automatically. When the detected temperature is higher than the LTPT, the controller will be working automatically (The LTPT is 0 °C by default and can be set within the range of 10 ~ -40 °C). |
| Carregar curtcircuit | When the load is short circuited (The short circuit current is ≥ 2 times the rated controller load current), the controller will automatically cut off the output. If the load reconnects automatically five times (delay of 5s, 10s, 15s, 20s, 25s), it needs to be cleared by pressing the Load button, restarting the controller or switching from Night to the Day (nighttime = 3 hours). |
| Càrrega de sobrecàrrega | When the load is overloading (The overload current is ≥ 1.05 times the rated load current), the controller will automatically cut off the output. If the load reconnects automatically five times (delay of 5s, 10s, 15s, 20s, 25s), it needs to be cleared by pressing the Load button restarting the controller, switching from Night to Day (nighttime = 3 hours). |
| Sobreescalfament del controlador* | El controlador és capaç de detectar la temperatura dins de la bateria mitjançant un sensor remot opcional. El controlador deixa de funcionar quan la seva temperatura supera els 85 °C i comença a funcionar quan la seva temperatura és inferior a 75 °C. |
| TVS High Voltage Transitoris | El circuit intern del controlador està dissenyat amb Transient Voltage Supressors (TVS) que només poden protegir contra alt voltagEls polsos de sobretensió amb menys energia. Si el controlador s'ha d'utilitzar en una zona amb llamps freqüents, es recomana instal·lar un descargador de sobretensions extern. |
*When the internal temperature is 81°C, the reducing power charging mode which reduce the charging power of 5%,10%,20%,40% every increase 1°Cis turned on. If the internal temperature is greater than 85°C, the controller will stop charging. But while the temperature decline to be below 75°C, the controller will resume.
