Solar battery brands
Which solar battery brands do we offer?
We offer a range of battery options at PureVolt, all carefully chosen based on how well they perform, how they integrate with the rest of your system, and the long-term support available. Some work best with specific inverters, others give you flexibility. Not all batteries can be mounted outdoors, so we've covered that too.
Battery capacity is measured in kilowatt-hours (kWh), which shows how much electricity a battery can store - for example, 1 kWh is the amount of energy used by a 1,000-watt appliance running for one hour. As a rough guide, a typical home in Ireland uses around 12 kWh per day.
Below is a full breakdown of what we offer, with links to datasheets and everything you need to know about performance, compatibility and capacity. We will very gladly recommend the best battery brand for your specific needs and circumstances though - there's no need for you to look into all the details yourself unless you particularly wish too. This is only here for those of a curious & technical nature who would like to investigate all the options with full technical details.
What is a Battery Management System (BMS)?
Think of the BMS like a computer that sits on the battery, to manage it as a system. It monitors the battery's state of charge, controls how power flows in and out, and protects the system.
In systems like Huawei or Sungrow, the BMS is a separate module that works alongside the battery stack. In other setups, the BMS may be built into the battery itself. The BMS is especially important when multiple batteries are connected.
1. Sungrow battery
Sungrow batteries are a solid, high-efficiency option, but they must be installed with a Sungrow inverter. The battery and inverter always stay within the same system family. These come with a 10-year manufacturer's warranty and a full 100% depth of discharge, meaning you can use all the battery's stored energy without limiting lifespan.
- Battery modules come in 3.2kWh blocks (you must install at least two for a 6.4kWh minimum).
- The maximum storage we can fit for this system is 19.2kWh.
- New 5kWh modules now available - install up to four together (20kWh).
- Requires a separate BMS (battery management system) module.
- Can be installed outdoors.
Please note: The older model Sungrow SBR3.2 HV batteries are discontinued. This means you can't buy additional batteries for systems with this model. The new Sungrow battery model is the SBS050 5kWh HV LFP.
Old model datasheet: Sungrow SBR3.2 3.2kWh
New model datasheet: Sungrow SBS050 5kWh
2. EcoFlow battery
EcoFlow batteries are a newer option with smart features and excellent cold-weather performance. These must be paired with an EcoFlow inverter, they're designed as a single ecosystem and do not mix with other brands. EcoFlow offers a 15-year warranty and a 95% depth of discharge.
- Each battery holds 5.1kWh, you can install up to three (15.3kWh max)
- Discharge and charge rates scale with each unit - one battery delivers up to 3.3kW export and 2.5kW import
- Can be installed outdoors - this battery also includes integrated heat pads to maintain optimal operating temperature, ensuring consistent charge and discharge performance in low ambient conditions.

3. Weco battery
Weco batteries are well-known for their flexibility and long-term reliability. They're compatible with a range of inverters, we commonly pair them with the Solis hybrid. These are modular, efficient, and retain 70% of their original capacity even after the number of cycles covered by warranty. Their warranty is set at 10 years, with a 100% depth of discharge.
- Each unit holds 5.3kWh, up to 3 installed as standard, or up to 15 for larger systems.
- Delivers up to 5kW of usable power, good for high-load homes.
- Expected to retain 70% capacity after 10 years of daily use.
- Must be installed indoors - outdoor installation not supported.

4. Dyness battery
Dyness offers a good balance of price to quality, and flexible installation options. The latest model we use is the H5B, and we still use the Dyness DL5.0C. Each unit holds 5.12kWh, and it can be expanded up to 10 units. Depth of discharge is 90%. These are suitable for outdoor use and ideal if you're after scalability without a high cost.
- Each battery provides 5.12kWh.
- Recommended charge/discharge at half capacity, so about 2.5kW.
- Expandable up to 10 units (over 50kWh total).
- Can be installed outdoors.
HSB datasheet: Dyness H5B
DL5.0C datasheet: Dyness DL5.0C
5. Huawei battery
Huawei's Luna 2000 battery series is smart, scalable and durable. It requires a Huawei inverter and a BMS module (battery management system). You can start small and expand later, or go larger from the start, the system supports stacking and parallel setups. The warranty is 10 years, and depth of discharge is 100%.
- Older Luna 2000 model: 5kWh modules, up to 3 in a stack (15kWh max).
- One Luna 2000 5kWh module outputs 2.5kW - expands to 5kW at 10kWh system.
- Newer version: Luna 2000 7S1 - each module stores 6.9kWh, and you can stack up to 3 for a total of 20.7kWh.
- Max charge and discharge rate for the Luna 2000 7S1 setup is 3.5kW.
- For larger systems: multiple stacks possible eg. 4 stacks of 3 (each stack needs its own BMS).
- Can be installed outdoors.
New model datasheet: Luna 2000 7S1
