OptiMate Solar - the world’s most efficient Solar Pulse Charger, Tester & Maintainer for both lead acid AND lithium batteries.

Charger by day, monitor by night.

The new OptiMate Solar range features a smart charger-monitor which automatically adjusts the charge according to the battery type and condition. Battery status information is provided while charging and when the battery is at rest overnight. The OptiMate Solar TM522-D1 2 amp smart charger controller has a 5 LED panel for comprehensive information on charge progress and battery status.

OptiMate Solar charge kits are fully automatic. Mount the panel in a suitable location to receive maximum sunlight, hook up the charger-monitor to the battery and walk away. No more battery problems.

When the panel receives sun, the SOLAR CHARGE LED blinks confirming solar power is being delivered and one of the four battery status LEDs (SAVE, CHARGE, MAINTAIN) indicates charge progress. OptiMate Solar converts low solar energy to a high pulse charge which improves solar charge efficiency. When night falls or if the smart charger-monitor senses no solar power is being delivered it changes into a battery monitor with one of the three charge status lights now indicating battery status every three seconds.

The 10W TM522-D1 kit (12V 0.8A max.) is ideal for all powersports vehicles. The weatherproof solar panel includes corner mounts for easy wall or roof mounting. Each kit includes a high intensity poly crystalline panel with a 2m power cable, an OptiMate O-1 weatherproof battery lead, an OptiMate O-4 battery clamp lead and the outdoor rated OptiMate smart charger-controller (TM522-D1) with a 1m charge cable.

    Amazing product

    Posted by Dale on 22nd Sep 2023

    I bought a 10W OptiMate Solar Charger nearly 12 months ago as my motorbike is in a shed with no electricity. I have not touched the bike since that date due to illness. I was wanting to take the bike out tomorrow so thought I had better check to see if the battery was alright, after all that time I was prepared for the worst. I checked the charger monitor and to my amazement it was green! I thought there is no way the bike would start but it did! First time!!!! I am truly flabbergasted after all that time it still maintained the battery in tip top condition.
