1. What is the exact power capacity and price per unit in the stack?

All our low voltage battery solution maximum charging power is 0.7C and maximum dicharge power is 1C. For example the 2.56kWh battery which is 51.2V 50Ah, so the single battery maximum charging current is 35A and maximum discharging current is 50A. However, the total current is limited by the cable and connector. The unit price is around 210 USD to 230 USD per kwh. It depends on how many you buy.

2. What is the price for a 15 kWh System? What is extra needed to inter connect systems?

For example our wall mounted 5.12kWh battery pack. You need there of them to achieve 15kWh. The total price is 3500 USD. The interner connections are power cables, communication cables and grounding cables.

3. Do yo provide us with the CE certification for import in Europe?

Yes

4. Does the battery has an automatic protection against overcharging or discharging lower then e.g. DOD 90%? and here we mean not just an alarm, but an effective protection to stop discharging @90%.

Yes. All lithium battery must be protected by BMS for a long lifespan. There are low SOC, low voltage(single cell, total) alarm and protection to protect batteries.

5. What are the shipping costs for a shipment to Belgium europe?

Based on 2021 Jan. offered price.It should be around 20 USD per pack for a full container from China to Belgium europe. However recently the sea shipping cost rises sharply and always change.

6. Do you we need an extra battery converter , which one can you recommend for your system?

Currently our battery has been BMS compitable with Growatt, Goodwe, Studer, Luxpower, Deye, Victron ect many brands.

7. we are working with solar edge as solar panel converter to the grid, can this system connect to it?

I am sorry we havn’t built BMS communication with solar edge, however if you can please help us with protocol. It won’t be a problem.
