In both series, it comes with solar panels, hybrid inverter, Lithium battery and cables & accessories. Solar Mini is the basic series with a 2.56kWh Lithium battery and a 2.2kVa hybrid inverter and 1000W~2000W solar panels. Solar Plus is the upgrade series with a 5.12kWh Lithium battery and 4.2 kVa hybrid inverter and 1000W~4000W solar panels.
Basically speaking, the ideal solution should be designed based on your current energy structure, including but not limited to total loads, peak load, daily power consumption and hourly distribution, roof area etc. Please directly contact TNL sales engineers for proper solutions at Email: sales@tnlafrica.com
Yes, to expand the storage scale of the energy, you could connect several units of batteries in series or in parallel. You could connect max. 4 pcs batteries in series to form a max. voltage 48V. You could also connect max. 4 pcs batteries in parallel to form a max. capacity of 800Ah.
Normally our continuous discharge current for 12V/24V batteries is 100A and charge current is 50A.
The 3.5 kVA inverter is good enough for 5 – 7bhk home and can run 15-20 led bulbs, 5-7 fans, 1 television, 1 mixer, and small 160-liter refrigerator during power cuts.
The inverter power for the Solar Max is 5kva and users could choose to parallel connect max. 10pcs of Solar Max to form a 50kva system while the batteries are scalable from 5kWh to 90kWh. The inverter power for the Solar Luxury is optional 6kva, 10kva while the batteries are scalable from 5kWh to 20kWh.
Lithtech Energy batteries are compatible with 90% inverter brands on the market, such as Victron, Growatt, Deye, SRNE, SMA, Megarevo, Voltronic etc.
Yes, it is ok to connect air conditioners with the Solar Max & Solar Luxury series. The detailed configuration depends on the total load of the houses or facilities. Normally, the chosen configuration power should be higher than the total load of the house.
The energy storage system working time depends on the total storage energy and the load consumption. For example, if users install a 5kva / 10kWh system, and the average power consumption is 2kva, the system could support maximum of 5hrs operation without grid or PV. If there is a PV connected, the operation time could be longer than 5hrs.
Yes, with the PV and battery energy storage system, there is no need for the users to connect the diesel genset anymore. The battery energy storage system could always work as a backup power for homes and facilities. Once the grid goes out, the inverter will automatically switch to supply by batteries without any shutdown of the loads.
No, users are not allowed to connect batteries with different voltage or capacity together. This will lead to damage of batteries or even damage to the property or people.
If users want to expand the energy, users could purchase the same model of Lithtech batteries from TNL and parallel connect them to the old system when all batteries are fully charged.
