Our First Huawei LUNA Series Battery Install…

We have been installing Huawei solar inverters for some time and are really impressed. Our teams love installing them, they work great and look awesome.

This week we completed our first Huawei LUNA battery install in Pattaya. This was a 10kWh configuration ( 5kWh +5kWh) with a controller. Max size per stack is 15kWh. For the Huawei LUNA series you need to use their Battery Back-Up Box, this is essentially an ATS to switch between utility power and battery power. When installing any Solar Hybrid system you will need to separate the loads and add critical loads to a new consumer unit. The output for this system is a 5kW single phase so you need to ensure that your critical/backup loads do not exceed this or you will overload the inverter and it will shut down. The Huawei Energy Storage System works differently from other Hybrid Systems that we have installed. There is no separate output cable that connects to your backup box, that is why you need Huawei’s Battery Back-Up Box – here you have Utility (PEA, MEA) as the primary, the Huawei Inverter as the secondary and the backup loads/critical loads.  The best way to use this system is as an off-grid system; this takes Solar PV first, Battery second and the Grid as the backup. 

The installation was fairly straightforward, the mounting kit and all components were in the package so just plug and play. Commissioning was a bit tricky as it was our first system but not difficult, the next installs will be easy. If you have just one Inverter and Battery then the setup is easy.

For this project, we installed two Huawei SUN2000 5kTL-L1 inverters, one connected to the battery and one AC coupled. This allows for 10kW of Solar PV for daytime loads and battery charging. We install a total of 30 LONGi 455Wp (mono half cut) Solar Panels, 15 per system.

The system can be monitored through the Huawei Fusion Solar application.

Finally, a solution for your backup power needs. The Alpha SMILE B3 Energy Solution can be used with an existing Solar PV system or can be used as a stand-alone critical power backup solution. The SMILEB3 is an AC coupled all-in-one battery energy storage system (BESS) that outputs 3000W of power. The integrated LiFePO. 4 battery is 2.9kWh, (2.8kWh usable) – which is expandable to 17.2kWh giving you plenty of power to manage your critical loads.

The SMILE-B3 can control the bi-directional flow of electric power, work under auto/manual & time-of-use (TOU) modes, charge/discharge the battery as per customer’s setting. All setting can be controlled through the Alpha ESS App. It also helps to achieve the optimal usage of renewable energy if you have an existing Solar PV System installed.

Frustrated with your Grid Tied System?

Do you have an existing grid-connected Solar PV system installed? Does it frustrate you when the power goes out and you’re left in the dark? The Alpha B3 solves this issue with a built-in lithium iron phosphate battery (LiFePO. 4 ) and the quick change over UPS mode. Never be in the dark again… Each system has its place and technology will forever evolve, adding on this system to take care of your backup power needs and charge it from your Solar PV system during the day.

Energy Storage, a few things to consider…

I have a Solar PV System installed, is it possible to add batteries to power my home?

The quick and simple answer is yes, but wait and read on before you rush out and buy some batteries, you don’t want to be disappointed. Do your homework and access your needs before you make the leap.

The first thing to consider is cost, at the time of writing this the cost for battery storage in Thailand is around Bt.15-18,000 per kW. So for a 10kWh Lithium battery that’s going to cost you Bt. 150,000 – Bt. 180,000 (pls 7% vat). On top of that, you are most likely going to need a controller and some other equipment and your Solar Inverter will need to be a Hybrid type and compatible with the batteries. That’s a lot to consider.

The second thing that you need to know is about connected loads, I will get to that in a minute. First, know that you can get a whole-house Solar Hybrid System but that is going to be two things; 1. Very Expensive 2. Very Big (in terms of space required for the batteries). So in this post, we will discuss the standard run of the mill home Solar Hybrid PV System. These systems are typically 5 or 10kW systems, which means that you have an output of 5 or 10kW. There are 30Kw Solar Hybrid Inverters on the market but these are mainly for Commercial Systems or very large residences. That’s where understanding loads come into play. Let’s look at a sample load set up for a standard three-bedroom house;

Sample Loads

  • Air Condition units (2), 12000 BTU 1700W
  • Swimming pool pump, 1500W
  • Water pump, 400W
  • Water heater, 6000W
  • Oven, 3000W
  • General power sockets, fan, router, charger etc.. 1000W
  • General lighting, all LEDs, 1500W
  • Computer, TV, refridgerator 1500W
  • Total Power Requirement 18,300W

Based on the above sample loads you can see that you would need a 20Kw Solar Hybrid Inverter to manage these loads. I know that not all the loads are on at the same time but we are looking at a theoretical maximum to give you an idea of what’s possible and what’s not. If you installed a 20kWh battery to the system then you would only get an hour of backup power. To cover a complete night, say 12 hours you would need 240Kwh to do that!

Critical Loads

The easiest way to add batteries to your system is to consider your critical loads. What loads are critical to you and your family should the power go out for an extended period of time. Or, if you are away what do you need to keep power to? Typically we suggest; lighting (low wattage LEDs), refrigeration, power for internet, phone chargers, fans etc., a house water pump and maybe one small Air Condition unit.

Let’s look at a critical load example.

Critical Loads

  • Lighting 1000W
  • Refridgerator 400W
  • House water pump 400W
  • General power 1000W

These loads, if all turned on would be around 2800W. If you had a 5kW Solar Hybrid Inverter and a 10kWh battery you would have around 4 hours of backup power. That’s more doable when you take a step back to consider what’s critical and what’s not.

Things to Consider before making a purchase

Consider why you want to have a backup power supply, what are the main drivers? Never wanting to be left in the dark, need to be online for work and cannot have any downtime, have some critical systems that need constant power, these plus many others are possible reasons why. What size system do you need? What is the total sum (watts) of all your critical loads? Make sure that the Solar Hybrid Inverter has enough power to support these loads. Time, how long to you need to have backup power? Typically three to four hours. So if your load is 5kW and you need four hours you will need 20kWh of batteries.
