Build a set

Choose a set-up, then stack it

Each set-up opens with its example. Take parts out and put them back, or press "Start from scratch" to begin from the base.

2. On-grid + battery

Store the solar power left over in the day for the evening and night. There is no Gateway, so there is no backup in a power cut yet (see set-ups 3–4).

How it is wired

1. Day: the panels power the home first and the rest charges the battery
2. Evening and night: the home runs on the battery and buys less from the grid
3. The Sensor in the main switchboard tells the system how much the home is using
4. No Gateway: no backup in a power cut yet

"Needed" cannot be left out; "can be added" is up to you. Battery size and number follow the design.

The parts

The parts of a Sigenergy set

SigenStor is 5-in-1: solar inverter, battery inverter, battery, EV charger and energy management in one stack. Sizes from Sigenergy's datasheets (W × H × D).

• EC (SigenStor EC)

  Top of the stack · 700 × 300 × 260 mm

  The SigenStor's inverter: turns solar power into household power and charges and discharges the batteries. TAMNIYOM sells 5 and 10 kW (single-phase) and 5, 10, 20 and 25 kW (three-phase)

• Sigen Hybrid

  On the wall · 99 mm slim

  A quiet wall inverter without fans. Start with solar only and add batteries and backup later; batteries connect through a SigenStor BC

• SigenStor BAT 6.0 / 10.0 battery

  Middle of the stack · 767 × 270 × 265 mm, both sizes

  Stores power for the evening, the night and power cuts. 6.02 / 9.04 kWh, 3 / 4.6 kW each. 1–6 per set, both sizes can be mixed. 62 / 78 kg

• SigenStor BC

  Top of the battery stack (Hybrid) · 765 × 109 × 260 mm

  Links the batteries to a Sigen Hybrid; needed when a Hybrid has batteries. Comes with the ground-mount base

• Ground-mount base (Installation Kit)

  Bottom of the stack

  The base the stack stands on, with adjustable feet so it stands straight on a hard floor. Every SigenStor uses one; with up to 2 batteries it can go on the wall instead

• SigenStor EVDC

  Under the EC · 700 × 270 × 260 mm

  DC car-charging module with a CCS2 plug, 12.5 kW (25 kW with the fast-charging licence), 7.5 or 10 m cable. With an EVDC the stack takes up to 5 batteries

• Sigen Gateway

  On the wall by the main switchboard

  Switches to backup power in a power cut; used in the backup and off-grid set-ups. Chosen by single / three-phase, the load on backup and the breaker size. In a power cut it supplies up to the inverter's size

• Sigen Sensor

  In the main switchboard

  A meter with clamps (CTs) around the cables that tells the system how much the home uses. Chosen by single / three-phase and the main cable's current

• Sigen CommMod NS

  Plugs into the unit

  4G SIM module for sites without internet; a data SIM is bought separately (normally the system connects by LAN cable or Wi-Fi)

Battery sizing

Sizing the inverter and batteries, simply

The same method as the installer training, in round numbers to show the idea. The team works it out properly from the electricity bill and the real appliances.

1. 1. Power used at once (kW) → inverter size

   Add up the appliances that run at the same time; the inverter must be bigger. On three-phase the inverter splits its power equally between the phases, so the busiest phase must stay within the power per phase

   Single-phase, 7 kW at once → 10 kW inverter · three-phase, 10 kW (phase A 2, B 5, C 3 kW) → 20 kW EC, which gives 6.67 kW per phase (10 kW gives 3.33 kW per phase, not enough for phase B)

2. 2. The batteries must keep up with the load

   Each battery can only give so much power: a 6.0 gives 3 kW, a 10.0 gives 4.6 kW. All the batteries together must give more than the load running at once without sun

   7 kW at once → at least 2 × 10.0 (9.2 kW) or 3 × 6.0 (9 kW) · three-phase 10 kW → at least 3 × 10.0 (13.8 kW) or 4 × 6.0 (12 kW)

3. 3. How long should the backup last (kWh)

   Load (kW) × hours = battery capacity needed (kWh)

   10 kW of backup for 4 hours = 40 kWh → at least 5 × 10.0 (45 kWh)

4. 4. The panels must make more than the home uses in the day

   The batteries only charge when the panels make more than the home is using in the day

   20 kWh used in the day: about 5 kWp of panels just covers it, nothing left to charge · about 6.25 kWp leaves about 5 kWh to charge the batteries

Examples from the Sigenergy installer training (June 2026) · kW = power (what is being used now) · kWh = energy (what was used in total; 1 kW for 1 hour = 1 kWh = 1 unit on the bill)

Before installing

Good to know before installing

The team surveys every site first. These points come from Sigenergy's installation training

• Where to put it

  It can go outdoors (IP66 against water and dust), best out of direct sun with nothing in the way, or in a well-ventilated garage. Away from bedrooms and daily work spaces, away from children, easy for the installer to reach

• Space around the stack

  For cooling: at least 40 cm above, 30 cm each side, 35 cm below and 40 cm in front

• Floor and wall

  On a hard floor, with the base's feet levelled so the stack stands straight. On the wall only with up to 2 batteries, on a straight, strong wall such as brick-concrete or concrete

• Places to avoid

  Attics, basements, places hard to reach, soft or uneven floors and leaning walls

• Internet

  Three ways: a LAN cable from the router, Wi-Fi (the antenna that comes with the unit) or a 4G SIM through a CommMod. Used to see and set the system in the mySigen app

• Settings at installation

  The installer sets the grid code for the area (PEA or MEA in Thailand) and the operating mode, such as maximum self-consumption or time-of-use (TOU)
