Yes, the generator can be connected to the load port (with a line selector, no possibity to charge the batteries with genset)

Which is the Peak Power of the inverter in Off-Grid Mode?2020-04-27T15:18:11+02:00

Jua Cabinet & Barrel

The inverter can provide up to 300% of its nominal capacity during 5 sec. at 25 ºC, enabling to provide the energy demands at the start-up of the devices powered by Jua products. Example: CA 25.24: 63 kVA during 5 sec.

Jua Light Cabinet & Light Barrel

The inverter can provide up to 150% of its nominal capacity during 10 sec. in mono-phase configuration and 160% during 60 sec. in three-phase configuration at 25 ºC, enabling to provide the energy demands at the start-up of the devices powered by Jua products. Example: LC 13.10.19: 16.5 kVA during 60 sec. in three-Phase.

Which is the output of the inverter in each configuration?2020-04-27T14:20:10+02:00

On-Grid Mode

The output of the inverter in on-grid mode is the nominal power of the inverter included in the equipment.

Off-Grid Mode

  • Jua Cabinet& Jua Barrel: The output of the inverter inlcuded in this equipment is the 100% of the nominal power during 30 minutes and 87.5% of the nominal power during. ExampleCA 25.24 provides 24 kVA during 30 min. and 21 kVA during 24 h.
  • Jua Light Cabinet& Jua Light Barrel: The output of the inverter inlcuded in this equipment is the 100% of the nominal power during 24 houra. Example: LCA 13.10.19 provides 13kVA during 24 h.
Which of the equipments are designed for On-Grid mode?2020-04-27T14:09:36+02:00

Jua Light Cabinet and Jua Light Barrel are not equiped with the technology able to work in 100% off-grid mode. They can work during a certain period of time in Off-Grid mode but they require the presence of the grid.

Which of the equipments are designed for Off-Grid mode?2020-04-27T14:06:20+02:00

Jua Cabinet and Jua Barrel are equiped with the technology able to work in 100% Off-grid mode, but they also can work in full On-grid mode.

When do I need to install batteries?2020-04-22T13:18:35+02:00

You will need to install a EnergyStorage System (ESS) either when the installation has a poor/null grid stability or part of the energy consumption occurrs during the night hours. The battery system size will strongly depend both on how intensive is this night energy consumption and the number of hours during which this demand is happening.

Is the battery pack included in the cabinet ?2020-04-27T16:17:17+02:00

Jua Cabinet

No, the battery pack must be purchased separately. Maximum battery sizing according to tecnhology: is possible to connect 96 kWh – 125 kWh – 133 kWh per single load cabinet. Soon this power will be increased

Jua Light Cabinet

Yes, 19” rack battery pack included. Battery sizing is from 2.4 to 19 kWh max per cabinet.

Which is the difference between CA & LC and BA & LB2020-04-27T12:46:36+02:00

CA and LC stand for Cabinet and Light Cabinet respectively. 

The equipment contained in the Jua Cabinet allows the customer to work 100% in off-grid mode. The battery pack must be acquired separately. Conversely the equipment of the Jua Light Cabinet enables the customer to work partially in off-grid, but also requiring the presence of the grid. In this case the battery system is included in the Light Cabinet.

The customer will choose the CA either when there is no grid present or the grid is not enough stable and will choose the LC when the grid is fully present or can stand for several hours.

BA and LB stand for Barrel and Light Barrel respectively. 

The equipment contained in the Jua Barrel allows the customer to work 100% in off-grid mode. In this case, the battery is included in the barrel. Conversely the equipment of the Jua Light Barrel enables the customer to work partially in off-grid, but also requiring the presence of the grid.

The customer will choose the BA either when there is no grid present or the grid is not enough stable and will choose the LB when the grid is fully present or can stand for several hours.

Which is the product code meaning ?2020-04-27T14:00:09+02:00
  • First Digit : Installable PV Capacity in kWp
  • Second Digit : Inverter Capacity in kVA
  • Third Digit : Battery Capacity in kWh
  • Example – LC 13.10.21 : 13 kWp PV Capacity, 10 kVA Inverter Capacity & 21 kWh Battery Capacity
