A Steinach timber plant is adding two 197 kWh batteries beside 520.76 kWp of roof solar - the CHF 35,000 is the panels, the 72% is an expectation, and the box only holds leftover noon
On 29 October 2026 SolarEdge said Leimholz Haag in Steinach is adding two commercial batteries to a rooftop system commissioned in June 2025. The roof is 520.76 kWp, about 54% of the plant's electricity, about CHF 35,000 a year and about 235,000 kg of CO2. The batteries are rated 197 kWh each, up to 394 kWh of surplus solar, with self-consumption expected to rise to 72%. Best Magazine reported the same figures on 30 October. No franc price for the batteries is printed. No inverter kilowatts for this site are printed. The batteries store surplus solar. They do not make power.
A timber plant already has panels on the roof. The new cabinets are there to hold the noon sun the plant does not use at noon. A battery does not make that sun. It stores it.
On 29 October 2026 SolarEdge said Leimholz Haag AG, a timber firm in Steinach, Switzerland, is adding two commercial batteries to a rooftop system commissioned in June 2025. The roof is 520.76 kilowatts peak. SolarEdge says it supplies around 54% of the firm's electricity, cuts about 235,000 kilograms of CO2 a year, and saves about 35,000 Swiss francs a year. Those three figures are printed for the panels that are already running. They are not printed as the result of the batteries.
The batteries. Two SolarEdge CSS-OD units, each rated 197 kilowatt-hours. SolarEdge says they are expected to store up to 394 kilowatt-hours of surplus solar from low-demand periods, for use when consumption rises, and to lift solar self-consumption to 72%, with peak shaving as a further cut in energy cost. 197 times 2 is 394, by our arithmetic. The page's "up to 394" matches that product of the two ratings. "Expected" and "up to" are the page's words. 72% is not a meter reading. The page says the batteries go in this autumn. It does not print a day.
Best Magazine's report on 30 October 2026 uses the same energy figures and says later this year. Neither page prints a franc price for the cabinets, a contract length, or the inverter kilowatts installed at Steinach.
The product range is wider than this site. Best Magazine says the CSS-OD 197 is a 197 kilowatt-hour lithium-ion cabinet, that deployments of the product can reach 4 megawatt-hours, and that the inverter output on the product is 50 kilowatts or 100 kilowatts. The "or" is a choice on a product sheet. The Steinach release does not say which inverter this plant is getting. 4 megawatt-hours is the top of a product range. It is not this order. This order is two cabinets.
What the solar already feeds, as SolarEdge describes the site. Buildings, machinery, and on-site production of nitrogen used in the firm's fire protection. The roofs sit at different heights and face east and west. A 25-metre storage tower throws a moving shadow. The installer is named as CE Concept Energy AG. Those are site facts on the vendor's page. They are not a price.
Peak shaving, in plain words. The battery pushes stored solar back when the plant's draw spikes, so the grid sees a lower peak. The page does not print the kilowatts shaved, the tariff, or the demand charge. A cut with no tariff is not a bill.
Best Magazine tracks the SolarEdge release. This note uses SolarEdge for the 29 October claims and Best Magazine for the 30 October retelling and the product's inverter range. No utility bill is attached. No independent meter report is attached.
A logistics yard already on this desk, in Aichi, is a different job: roof solar and a battery with the yen left blank. Steinach prints a franc figure, and the franc figure is for the panels.
Analogy: the roof is the tap. The cabinets are a bucket for what the tap spills at noon. CHF 35,000 is what the page says the tap already saves. The bucket has no price on this page, and 72% is a figure for after the bucket is in.
Good: A vendor date, a second report the next day, a named plant, a panel size, a panel saving, and a battery size that multiplies cleanly.
Bad: The saving, the 54% and the CO2 line are the solar, not the batteries. 72% is expected. No battery price. No switch-on day. No site inverter kilowatts. Both reports start from the vendor.
Ugly: Putting CHF 35,000 on the battery. Reading 72% as a result already measured. Reading 50 or 100 kilowatts as the Steinach order. Reading 4 megawatt-hours as this plant. Treating the cabinets as a supply that works after dark with nothing stored from the roof or the grid.
Soft next step: keep CHF 35,000 on the solar line, put 394 kWh on the battery line, and leave the battery's francs and the inverter kilowatts blank.
Source: SolarEdge, 29 Oct 2026 - Leimholz Haag batteries at Steinach. Primary for the 29 October date, Leimholz Haag AG in Steinach, the June 2025 commissioning of 520.76 kWp, around 54% of electricity, about CHF 35,000 a year, about 235,000 kg of CO2 a year, two CSS-OD batteries rated 197 kWh, up to 394 kWh of surplus solar, an expected rise in self-consumption to 72%, peak shaving, installation this autumn, buildings and machinery and on-site nitrogen, east- and west-facing roofs, a 25-metre tower, and installer CE Concept Energy AG. The page does not print a franc price for the batteries, a contract length, a calendar day, or the inverter kilowatts at this site. 197 times 2 equals 394: that product is our arithmetic, and it matches the page's "up to 394 kWh". Best Magazine, Lois Giles, 30 Oct 2026 - battery storage at Leimholz Haag. Primary for the 30 October retelling of the same energy figures, the phrase "later this year", and the product description of the CSS-OD 197 as a 197 kWh lithium-ion cabinet with deployments up to 4 MWh and inverter output of 50 kW or 100 kW. Best Magazine does not say which of those inverter ratings Steinach is getting. The 4 MWh line is a product range, not this order.
