4.4.2 Description of Parameters under Group 1 - CHARGE CURVE
4.4.2.1 BULK CURRENT (Table 4.3, Screen No. 1)
Parameter "BULK CURRENT" sets the maximum charging current during the Bulk Charging Stage. The default value
is (a) 20A for EVO-1212F / 1212F-HW, (b) 20A for EVO-1224F / 1224F-HW, (c) 40A for (i) EVO-2212 / EVO-3012 /
EVO-2224 / EVO-4024 and (ii) EVO-2212E / EVO-3012E / EVO-2224E / EVO-4024E and (d) 20A for EVO-4248SP.
Normally, Lead Acid batteries should not be charged at very high Bulk Current as this may damage the batteries due
to overheating and cell degradation. Normal Bulk Charging Current is in the range of 10% to 20% of the Ah capacity
of the battery bank at C/20 Discharge Rate. Lithium Ion Batteries can be charged at much higher Bulk Current as
compared to Lead Acid type. Check with the battery manufacturer regarding recommended Bulk Charging Current for
your battery bank.
!
CAUTION WHEN SETTING "BULK CURRENT" FOR MODEL EVO-4248SP!
When the AC input voltage is 120 VAC Single Phase, the Bulk Current setting of Model EVO-4248SP should
be reduced to <30A. This will prevent the unit from overheating due to unbalance when charging the
battery bank and running pass-through loads from both L1 & L2 legs of 120/240 VAC Split Phase output
(See Section 3.6.1.2 of the Owner's Manual for Model EVO-4248SP).
!
ATTENTION LORS DU RÉGLAGE DU «COURANT EN VRAC» POUR LE MODÈLE EVO-4248SP!
Lorsque la tension d'entrée CA est de 120 VCA monophasé, le réglage du courant de masse du modèle
EVO-4248SP doit être réduit à <30A. Cela empêchera l'unité de surchauffer en raison d'un déséquilibre
lors de la charge du groupe de batteries et de l'exécution des charges de passage à partir des deux jambes
L1 et L2 de la sortie de phase divisée 120/240 VCA (Voir la section 3.6.1.2 du manuel d'utilisation du
modèle EVO-4248SP).
