Batteries & storage

Not necessarily. If you use most of your electricity during the day — refrigeration, a pump, air conditioning, machines — your panels feed your loads directly, and a battery would only add cost and conversion losses. It earns its place when your consumption peak falls in the evening, or when you need power to stay on through outages. We read your consumption curve hour by hour before recommending anything.

On paper, a Dyness LFP battery takes 6,000 cycles at 90% depth of discharge, with a 10-year warranty and at least 70% of its capacity retained. Count one cycle a day and those 6,000 cycles alone span more than sixteen years. But a battery also ages while it sits — roughly 1 to 2% of capacity lost per year, even unused. It is this calendar ageing that usually decides matters in the end, bringing the real working life down to 12–15 years in the Moroccan climate. The way to claw back some of those years: keep the battery in the shade, ventilated, between 15 and 35 °C.

The tiers map to distinct needs. 5 to 10 kWh: basic night-time backup, or keeping a few essentials running through an outage. 10 to 20 kWh: full evening self-consumption for an average household — the day's solar surplus covers most of the night-time load. 20 kWh and up: near-autonomy, remote sites, or 2 to 3 days of cover with no sun. Our Dyness modules stack in 5 kWh steps, so we set the capacity to the evening dip you need to cover, not to a marketing tier. A dedicated guide walks through the calculation.

Yes, if the hybrid inverter is set to EPS (Emergency Power Supply) mode. Deye SG-series inverters switch over almost instantly (about 4 ms) with no extra box — comparable to a UPS. How much power you have during an outage depends on the installed capacity and on the loads wired to the backup circuit. Don't confuse this with a plain on-grid inverter, which also shuts down during an outage, for safety.

In Morocco, law 82-21 (in force since June 2026) caps grid injection at 20% of annual output, and the ANRE buy-back rate of 0.18 to 0.21 DH/kWh is published for the medium, high and very-high voltage (MV/HV/EHV) regimes — the low-voltage (LV) declaration regime, the one that covers almost every residential installation, has no published rate yet (see /loi-82-21). Yet a kWh bought from the grid costs you between 0.90 DH (first tier) and 1.66 DH (heavy use). In other words, until the LV rate is published, a kWh stored and self-consumed in the evening has a certain value, while an exported kWh currently has no guaranteed value for a residential household. So the order of priority is: (1) consume directly by day, (2) store for the evening, (3) export the balance, capped at 20%, without counting on it financially. Don't oversize your batteries to export more — it doesn't pay.

The built-in BMS manages charge and discharge automatically, with no manual intervention. Real-time production monitoring reports the battery’s state continuously; a scheduled maintenance visit can be added as a contract, but its exact cadence, response time and price are still pending founder validation — no figure published until it is settled.

Capacity — and therefore price — follows your evening consumption dip, not a catalogue tier: our Dyness modules stack in 5 kWh increments, and we stack just enough modules to cover what your panels no longer provide once the sun has set.

The lithium-iron-phosphate (LFP) battery itself, its native CAN BMS dialogue with the Deye hybrid inverter that drives charge and discharge, the wiring, and real-time production monitoring access to track its state.

Accidental damage or an external impact, an intervention by a third party not authorised by Taqinor, a clear lack of maintenance, a force-majeure event and normal wear beyond the guaranteed thresholds (≥ 70 % capacity retained at 10 years). Indicative list, to be confirmed — see the Warranties page.

The same process as a new installation: first reading your hour-by-hour consumption curve to check storage is justified, then a direct exchange with a technician, finally the technical visit that confirms the capacity (in 5 kWh modules) and the quote.

10 years, with at least 70 % of initial capacity retained over that period — more than 6,000 cycles at 90 % depth of discharge. Same on-the-spot activatable warranty rule as the rest of Taqinor’s tier-1 equipment (sourced through official distributors in Morocco).
