I have recently placed several orders with Bimble Solar for the supply of Panels and Grid tied inverter system. Panels were initially out of stock but I was kept informed of progress. The Growatt inverter equipment was provided ex-stock and all is functioning well on our first solar implementation (1.2kw on a shed roof!) I intend to double up on the Perlight panels (295w) in the new future, and will go to Bimble again.
New XTRA series - 3rd Generation MPPT - Budget Model
For 12V Solar System: 260W solar panel (60V for max input voltage)
For 24V Solar System: 520W solar panel (60V for max input voltage) *Solar Panels must be 36cell (2 in series) or 72 Cell (1 in series) for use on a 24 Volt battery system*
No Fan for silent operation, great for vans, boats or any live in spaces
Budget Model with no display. Can connect MT50 for remote display.
New XTRA series has Lithium battery support (set via PC cable only)
The XTRA tracer models have a current limiting function, you can connect 1.5 times the rated power to the controller so if your on a budget you can use a smaller controller with more panels so that you get more power in winter or low light but don't risk overloading the controller in the summer. The output will be limited to the max listed above.
New EPEver (Tracer) series is EPsolar’s third generation of MPPT controller.
XTRA series are advanced maximum power point tracking (MPPT) charge controllers, for off grid photovoltaic systems, with display unit.
In order to maximise the energy harvest from PV arrays and simultaneously minimise the power loss within a wide range of operating conditions, XTRA series apply an advanced smart algorithm which results in up to 30% higher efficient charging, compared to a conventional pulse width modulation (PWM) charge controller. Xtra series controller have limit protection function on charging current &charging power, as well as auto derating power operation at high temperature; the above protection ensure the stability of system even at exceeded rated PV power and over temperature conditions.
Protection class IP32 and isolated RS485 communication port further improve the controller’s reliability under different application requirements. XTRA series controllers incorporate a self-adaptive three-stage charging algorithm based on a digital control circuit, which eeffectively prolongs the lifespan of battery and significantly improve the system performance. It also has extensive electronic protection for overcharge, over discharge, PV&battery reverse polarity and etc. to ensure the sustainability and durability of the o-grid solar system.
