Lithium solar battery 5.12Kw Voltem 48V

Description

The 5120W Voltem 48V Lithium Solar Battery is a Lithium-Ion Phosphate battery internally constituted by LiFePo4 modules, with a standard 19″ rack format. This makes it easy to expand the system when needed, up to 16 modules without HUB access. This modularity makes it suitable for both small and large accumulation systems, occupying less space.

CompatibilityBattery Compatibility Lithium 5120W Voltem with Inverters

It can be connected to many of the inverters on the market. It includes numerous communication parameters that enable this battery to share its charge data and thus operate correctly and safely. It has a Canbus communications port and RS485 to communicate directly with the inverters. It has built-in intelligent BMS, compatible with more than 30 Inverters from brands such as those listed below:

• Growatt Invesores Growatt: Compatible with Growatt MIC Series 750-3300 TL-X / Growatt MIN Series (2500-6000) TL-X / Growatt Hybrid SPH 3000
• Victorn Inverters: Can work with multiplus and quattro models
• Sofar Inverters: The entire range of Sofar hybrid 48 volt inverters can operate with communication with the Voltem 5120W battery. The manufacturer Sofar recommends a minimum of two units.
• SolarEdge inverters: include a variety of options such as SE 3K – 10K / HD-Wave single-phase models. Or the three-phase models such as SE 12.5K – 27.6K, SE 25K / 30K / 33.3K, SE 50K / 55K / 82.8K
• Deye Inverters: including all 48V Deye range can operate with communication with 5120W Voltem Lithium battery.
• Axpert Voltronic Inverters: The entire range of 48 volt MK, MKS, MKS II, VM and VM IV hybrid inverters are compatible with the 5120W Voltem lithium battery and operate without communication.

Mounting and parallel connection of several Voltem 48V lithium batteries

The Voltem 5120W solar lithium battery has the option for wall mounting. It can also be mounted in parallel with more modules using the Ethernet communication cable included with each battery. We can parallel up to a maximum of 16 batteries without HUB access (up to 72.96 kWh).
 

Outstanding benefits of the lithium solar battery Voltem

The 5120W Voltem 48V lithium solar battery is a state-of-the-art lithium accumulator that has many advantages over lead acid batteries.

1. Low weight and volumeThanks to its high energy density, we have stored 5.1 kW in only 49 kg of weight. For a lead-acid battery we need about 98kg for the same capacity. The size is also smaller so we need less space and can even make portable systems in applications that require it thanks to its greater manageability.
2. High number of cycles: Lithium has qualities of use far superior to lead acid. So if a tubular-plate lead-acid battery has about 1500 cycles at 80% discharge, the Voltem lithium battery delivers more than 6000 cycles at 95% discharge.
3. Maintenance-free: The lithium battery does not require any maintenance or refilling with liquids during its entire service life. As it is a sealed module, it does not give off gases or odors, so it can be installed indoors. It should be prevented from working in extreme temperature and humidity environments in order to extend its life as long as possible.
4. It offers better value for money. It has a much greater depth of discharge, reaching up to 95% during 6000 cycles.
5. Increased loading speedOne of the main advantages is that the lithium battery can be charged at a rate of 2C, even if necessary at 1C. Therefore, if we have a charger with sufficient power, we can charge the battery in 2 hours from a total discharge. And if necessary, a full charge can also be carried out in 1 hour. The BMS (Battery Monitoring System) automatically performs a balancing to ensure that all batteries have the same charge.
6. Increased safety, as it has a multi-protection system against temperature, voltage, SoC and SoH.
7. Compact and modular design allows for easy installation, expansion and upgrading.
8. Wide range of working temperatures from -10ºC to 50ºC without affecting its useful life.
9. Depth of discharge at 95% DOD with no memory effect, no voltage drops and unaffected by temperatures.
